Service TrainingSelf-study Programme 422Mobile Phone with Bluetooth® Design and FunctionEveryone knows the Vikings. They were battle-tried warriors, who kept the Old World on its toes for around 250 years starting in 793A.D. when they attacked England in their seagoing long boats. They also discovered and colonised new worlds. But would you associate them with a modern, wireless communication technology called Bluetooth®? There is indeed an association because the name of this system is a small tribute to the Viking king Harald I Bluetooth Gormson (Harald Blåtand in Danish) by the Bluetooth® software developers. As the Danish and later Norwegian king, he pushed for the Christianisation and unification of the north and was considered to be very communicative. The use of the name Bluetooth also underlines the large number of Scandinavian companies involved in the development of Bluetooth®.S422_068For current testing, adjustment and repair The self-study programme portrays the design and function of new developments. instructions, refer to the relevant service literature.

They have the task of ensuring we can be reached at all times, entertaining us and helping us organise our daily schedule. They are therefore also increasingly being combined with the electronic equipment used in today’s cars. These devices need to be integrated into the technology system of the equipment so that you can operate them using the controls provided in the vehicle, for example, the multifunction steering wheel and the central display and operating module of the radio. This is the only way to reduce the risk of the driver being distracted from driving when he operates these devices. Due to the wide range of connectors and interface types used by the different manufacturers, it was a good idea to use a standardised, wireless connection to connect these devices. The industry standard Bluetooth®, which was developed in the nineties, has established itself as a short-range wireless networking system thanks to its high flexibility and robustness. These networks, which have a very limited coverage, are also known as WPANs (Wireless Personal Area Network).S422_001The number of mobile phones on the market is large as is the range of telephone preparations supplied by Volkswagen for specific vehicle models and equipment. Therefore we cannot cover all variants in the operating instructions provided in this self-study programme. All information therefore refers to the Nokia 3109 mobile phone and should be considered as an example. For exact details and information on the compatibility of devices and their operation, please consult the corresponding customer service literature, the online information in Volkswagen Service and the operating manuals for the devices used.4Microwave spectrum with the 12 ISM frequency rangesISM frequency range 2.402GHz to 2.483GHzBluetooth® transmits and receives in one of the twelve globally approved ISM frequency ranges (Industrial Scientific and Medical Band) within the microwave spectrum. These special frequency ranges may be used without radio licenses and authorisation. A frequency range that is defined for a specific purpose is also called a band. Therefore we also talk about ISM bands. The ISM band in the frequency range from 2.402 to 2.483GHz is used for Bluetooth® operation.Microwave oven, WLAN, wireless remote controls, Bluetooth S422_026COMPLETE ELECTROMAGNETICSPECTRUMOutput of data packets device 1Frequency hopping in ISM bandThe robustness of the Bluetooth® data connection when exposed to electromagnetic interference results from a frequency hopping process. The available frequency range of the ISM band used is divided into 79 channels for this process. The connected devices hop back and forth between these channels 1,600 times per second while transferring the data packets. Before starting the transfer, the devices automatically decide which channels they will use in which sequence to transfer the data. As long as the whole width of the ISM band is not affected by interference, the effect of interference on the data transfer is limited because the impairment can only take affect for a fraction of a second due to the constant change of frequency.S422_027Receipt of data packets device 2You will find detailed information on the technical basics of Bluetooth® in self-study programme 345 “Universal Mobile Phone Preparation”.5BasicsUp to eight devices can be connected in a small network using data transfer on the basis of Bluetooth®. These networks are also known as piconets. Within a piconet, one device acts as the master and the other (up to seven Bluetooth® devices) as slaves, i.e. they are subordinate to the master.S422_003Master device Slave device Unused connectionWithin a piconet, the devices use two different transmission types. A circuit-switched, synchronous connection-oriented link (SCO) with a data rate of up to 64kbit/s is used exclusively for transmitting speech. For other data, for example, music data where it is possible to transfer all information in small data packets, packet switching or an asynchronous connectionless link (ACL) is used. This means that the receiving device can store the data packets as they arrive one after the other and then finally reassemble all information to deliver it as a whole.Asynchronous connectionless link (ACL)Synchronous connection oriented link(SCO)S422_0056A Bluetooth® device can be logged onto several piconets, but can only operate as the master in one network. It is also technically possible to link up to eleven piconets. This is referred to as a scatter network. Since this function has not yet been standardised, it is currently not used in the motor industry.S422_006Only one channel is set up at a time. One of the slave devices can communicate with the master device through this channel.Master device Slave device Unused connectionBluetooth® piconets have a high level of protection against tapping and unauthorised access to the networked devices by third parties. On the one hand, the transmission power of 1mW (TRANSMISSION CLASS III) limits the range to approximately ten metres so that hackers need to be within this distance. On the other, they need to know the Bluetooth® address of a connected unknown device. When a connection is set up, a passkey is also required, which is made visible only to direct users. 10mPasskey = ??S422_0077Hardware ComponentsHow do you recognise Bluetooth®-compatible devices?Bluetooth® is a registered trademark that also has its own logo. In most cases, the manufacturers of mobile phones, PDAs and consumer electronics use this logo on their products to indicate that they are Bluetooth® compatible.S422_004S422_008In addition, there are also further indications on the devices, for example, on the Volkswagen “3C0 Premium” adapter set, which has the “Activate Bluetooth®” label alongside the Bluetooth® logo to show that it is compatible.Bluetooth® logoActivate Bluetooth®Bluetooth® profilesSince Bluetooth® was and will also continue to be subject to development, Bluetooth® compatibility alone is not a one hundred percent guarantee that a device can actually be paired with the mobile phone preparation. And, even if it does work, not all functions will necessarily be available. To achieve this, a Bluetooth® device like, for example, a Bluetooth® mobile phone also needs to support different software profiles, which regulate data transfer between itself and the paired devices and make functions available.Indication that the device is suitable only for Bluetooth® networking.The following table shows you which profiles a mobile phone needs to at least support for use with the “UMPP Standard” or “UMPP Premium”. The profiles specified under “optional” expand the functions of the mobile phone allowing them, for example, to be selected with the vehicle controls.UMPP Profile HFP rSAP A2DP PBAPStandard Required OptionalPremium Required Optional● ● ● ●You will find descriptions of the HFP and rSAP profiles in self-study programme 345 “Universal Telephone Preparation”.8PBAP (Phone Book Access Profile) PBAP allows you to select and use individual phone numbers or any telephone books that are stored in the mobile phone. Individual entries are transferred as electronic business cards (vCard). The data format used for the business cards is “vcf” (vCard file) and is also used by many e-mail programs and organizers.BPAPCAN data busExample UMPP PremiumS422_074A2DP (Advanced Audio Distribution Profile) This profile allows music to be transferred on an audio channel in stereo quality, for example, from an MP3 player via the mobile phone and the universal mobile phone preparation to the vehicle audio loudspeakers, only in one direction (unidirectional transmission).A2DPA2DPCAN data busS422_012 Example UMPP StandardDepending on the manufacturer, it is also necessary to activate the data protocol or also the profiles used via the device menu. The operating manuals from the manufacturers provide information on this. Depending on the device type, current profiles can also be installed later on. Please also refer to the manufacturer information about this.9Hardware ComponentsBluetooth® mobile telephones from VolkswagenNokia 3109 Bluetooth® mobile phoneThe Nokia 3109 is one of four Bluetooth®-compatible mobile phones from the Volkswagen accessories range.Technical features (extract) Tri-band mobile phone (supports GSM 900, GSM 1800 and GSM 1900) Colour display with 128 x 160 pixels Integrated browser for mobile Internet access Integrated music player for MP3, MIDI, AAC and WMA among others Integrated video player for MP4, H.263 and H.264 Approx. 8.5Mb internal memory for user data Up to 2Gb memory with microSD memory card-All information on operation, for example, pairing Bluetooth® devices, that is provided in this self-study programme refers exclusively to this specific mobile phone.S422_015Further Bluetooth® mobile phones from the Volkswagen accessories rangeNokia 6300/Nokia 6500 classic Nokia 6021 Sony Ericsson W890iNokia 6300/ 6500 classic S422_016Nokia 6021 S422_021Sony Ericsson W890i S422_017Make sure that all devices that are to be used together via the Bluetooth® interface, for example, mobile phone preparation (UMPP), mobile phone and headset, are compatible with each other. You will find more detailed information about this under Volkswagen Accessories.10Mobile phone preparationsVolkswagen currently supplies two types of mobile phone preparation: “UMPP Standard” and “UMPP Premium”. The mobile phone communicates with the vehicle electronics via the mobile telephone operating electronics control unit. If the necessary profiles are supported by the Bluetooth® devices involved, limited operation of these devices via the vehicle controls depending on the equipment or via the radio or radio/navigation unit in the vehicle is possible. In this context, limited means that it may not be possible to access all menus and configuration options in the paired Bluetooth® device with the vehicle controls. The battery of a Bluetooth® device can only be charged from the vehicle onboard voltage supply, e.g. a Bluetooth® mobile phone with the Premium mobile phone preparation, if it is placed in the cradle (available as an option only for Passat, Passat CC and Touareg).The basic difference between the two is which device acts as the master in the piconet and carries out the pairing with the other devices (slaves) within the network. If you are using the “UMPP Standard”, pairing is performed on the mobile phone. This means the telephone searches for the UMPP and sets up the connection. The mobile phone is therefore the master. If you are using the “UMPP Premium”, the control unit searches for available mobile phones or other Bluetooth® devices. This means the control unit sets up the connection and is the master in the vehicle piconet. A mobile phone preparation (UMPP) consists of: - the mobile telephone operating electronics control unit, - the base plate, - the cradle or the universal pairing adapter and - the telephone aerial system.The Volkswagen accessories brochure “Volkswagen Mobile Phone Preparation and Bluetooth®” provides a detailed overview of the possible device combinations for cradles and mobile phones. Furthermore you will also find information about this topic on the Volkswagen accessories website.11Hardware ComponentsConnecting the Bluetooth® network to the vehicle electronicsDepending on which mobile phone preparation (UMPP) is fitted in the vehicle, the mobile phone or the UMPP can function as the master to which further devices can be assigned as slaves. This could, for example, be a headset used as a hands-free system, an MP3 player as a music source and/or a PDA as additional telephone book. Since the equipment options related to the UMPP vary, the networks set up with the different telephone preparations may use different controls and display units in each vehicle. The system connections set up with the “UMPP Standard” and “UMPP Premium” are used as examples in the following section.Bluetooth® network with the “UMPP Standard” mobile phone preparationThe control unit J412 logs onto the mobile phone as a slave with this UMPP.

These are: - the 3C0 Standard adapter set up to model year 2007 and - the 3C0 Premium adapter set (includes standard scope from model year 2007). The universal pairing adapter set from Volkswagen accessories can be used by users of Bluetooth® mobile phones that do not fit in the 3C0 adapter sets, but do support the hands-free profile.3C0 Standard adapter setThere are two versions of this cradle with and without integrated voltage transformer for charging the mobile phone battery. It converts the onboard supply voltage from 12V to the 6.5V Nokia charging voltage. The cradle with integrated voltage transformer is required only for Nokia mobile telephones and vehicles produced from week 44/2007. This is because the UMPP after this date no longer supplies the special Nokia charging voltage, but 12V instead. Up to week 44/2007, the UMPP supplies the special Nokia charging voltage via a separate output so that the cradle does not need an integrated voltage transformer. The cradle without integrated voltage transformer is therefore required for these Nokia mobile phones. In addition, there are further distinguishing features that depend on the production date of the vehicle and the UMPP.For vehicles up to week 21/2007 The mobile phone can only be used with the UMPP if the mobile phone is inserted in the adapter set. The connection between the mobile phone and UMPP is made via the contacts on the adapter set, i.e. by wire. Connecting the telephone via Bluetooth is not supported with the exception of the cradle for the Nokia 6310. If you do not place the telephone in the adapter set, it cannot be used with the telephone preparation.CradleS422_01014For vehicles from week 22/2007 Mobile phones without Bluetooth® can no longer be used as standard in vehicles from week 22/2007. The audio data and control information is no longer transferred between the mobile phone and UMPP via the contacts in the phone cradle supplied with the adapter set, but only wirelessly via Bluetooth®. Only the info and breakdown call functions are still performed over a wire connection between the adapter set and UMPP.3C0 Premium adapter setCradleIn the 3C0 Premium adapter set, the plastic housing that clicks into the base plate serves only as a phone cradle and charging holder. The info call and breakdown call functions are performed via the contact pins in the adapter set as on the 3C0 “Standard”. The telephone functions can be controlled on the mobile phone or, if you have the UMPP “Premium”, also via external controls like the multifunction steering wheel, the button panel or the radio/navigation system controls. The Bluetooth® mobile phone also works if it is not placed in the cradle. Technically it is preferable, however, to place the telephone in the cradle because there will then be a wire connection to the GSM module.S422_009Info callBreakdown callThe GSM module is integrated in the mobile telephone operating electronics control unit and connected to the more powerful external aerial. In this way, a considerably more interference-free reception will be achieved. The mobile phone needs to be logged onto UMPP correctly, however. (see Bluetooth® pairing)The mobile phone will not be charged during use in the vehicle if it is not placed in a suitable holder or charging cradle.15Hardware ComponentsVehicle-specific adapter setsThere are specific adapter sets or mobile phone charging cradles for numerous vehicles and vehicle equipment lines like, for example, the Passat model year 2006. The Bluetooth®-compatible mobile phone is kept in the storage compartment under the centre armrest depending on the equipment and is also controlled from there.S422_072Universal pairing adapter from VolkswagenThe adapter can be used to connect Bluetooth® mobile phones to the “UMPP Standard” if no special brackets or charging cradles, which fit on the base plate of the mobile phone preparation, are available for them. In order to use the Bluetooth® function with the “UMPP Standard” in vehicles from week 22/2007, the universal pairing adapter from Volkswagen is required. It is fitted in place of the adapter set into the base plate of the mobile phone preparation. Inserting it activates the Bluetooth® function of the UMPP so that the UMPP can log onto the mobile phone. The info and breakdown functions are available via the buttons on the pairing adapter. It is not possible to charge the mobile phone when using this adapter.Pairing adapterS422_019 Base plate of mobile phone preparationThe universal pairing adapter from Volkswagen can only be used for the “UMPP Standard” mobile phone preparation.16Using Bluetooth®Pairing Bluetooth® devicesTo operate a mobile phone or other devices on the piconet with or from the UMPP, these devices need to be logged onto the Bluetooth® network. You can also say: “The devices need to be paired.” This procedure involves the following steps: Activating the Bluetooth® interface on the devices Making the devices visible for the pairing process Pairing the devices by entering the passkeyBefore the first or subsequent pairing, the following conditions need to be met always and regardless of the UMPP type: The vehicle is stationary. The ignition key is inserted. The ignition is switched on.Activating the Bluetooth® interface on the mobile phoneElectronic devices like mobile phones, PDAs etc. do not necessarily have to use Bluetooth® to exchange data since they also have other interfaces, for example, USB. Therefore you normally need to enable the Bluetooth® interface manually in these devices. This is done in the settings menu of the device you want to pair.S422_033 SettingsIn the Nokia 3109 mobile phone, you will find this option in the main menu under “Settings” and then the “Connections” entry. Select the “Bluetooth” entry.SettingsSpeed Dial ConnectionsOption SelectConnectionsBluetooth Infrared Packet Data Data Transfer USB Data CableSelectBack S422_034The rSAP profile needs to be activated separately on the telephone if you are pairing it with the “UMPP Premium”. Please refer to the operating instructions for the mobile phone about this.SelectBack S422_03517Using Bluetooth®Select “On” and confirm the selection. Bluetooth® is now enabled on the mobile phone as on the “UMPP Standard”. On the “UMPP Premium”, the Bluetooth® interface is permanently enabled so you do not need to activate it manually when pairing the mobile phone.BluetoothOn OffBluetoothOn Bluetooth enabled.Select S422_035 S422_036Making the devices visible for the pairing processBluetooth® devices can only be discovered by other Bluetooth® devices and displayed as new communication partners if they are “visible”. This also applies to the mobile phone and the mobile phone preparation. However, the devices need to be set to visible only for the first pairing procedure in a piconet.Setting the Nokia 3109 to visibleOnce you have enabled the Bluetooth® interface, the mobile phone indicates whether it is currently visible in the “Bluetooth” menu. Selecting “My phone’s visibility” takes you to a list of options where you can choose from “Permanent visibility”, “Temporary visibility” and “Hidden”. If you select “Temporary visibility”, the user will have two minutes to carry out the pairing process. If you select the “Permanent visibility” entry, there will be no time limit for the pairing procedure. However, for security reasons, you should not forget to set the mobile phone to “Hidden” again once you have completed pairing.BluetoothBluetoothMy phone’s visibilityHidden Select S422_038 VisibilityPermanent visibility Temporary visibility HiddenBluetoothBluetoothSelect Back S422_040My phone’s visibilityPermanent visibility Select Back S422_03818Making “UMPP Standard” visibleThere are three ways to set the “UMPP Standard” to visible. Before you start pairing the vehicle needs to be stationary. This requirement also applies to the “UMPP Premium”.1st possibility The Bluetooth® connection of the UMPP is visible for five minutes after you switch on the ignition. After this time or if you start driving, the Bluetooth® connection of the UMPP will be set to hidden again.Ignition “on”Visible in Bluetooth® networkS422_028 for 5 minutes2nd possibility Press the info button first and then the breakdown button in succession within five seconds. The Bluetooth® connection of the UMPP will now be visible again for 5 minutes. This is signalled by a confirmation tone.S422_029 One after the other within 5 seconds Visible in Bluetooth® network for 5 minutes3rd possibility Alternatively you can also press the telephone button on the multifunction steering wheel twice in quick succession to set the Bluetooth® connection to visible. Again the visibility is signalled by a confirmation tone.2xIn quick succession Visible on Bluetooth® network S422_030 for 5 minutes19Using Bluetooth®Making “UMPP Premium” visibleIn addition to the three possibilities described, the “UMPP Premium” can also be set to visible for three minutes via the telephone menu. Open the telephone menu in the dash panel insert display and then select “Settings”.Telephone Bluetooth Settings BackAfter you confirm the selection with the OK button, the menu item “Visibility” will take you to the appropriate menu.Telephone New user Visibility BackS422_041There you have the two options “Yes” and “No” under the “Switch on visibility” question. You can make the UMPP temporarily visible with “Yes” and the OK button. It is not possible to make the UMPP Premium constantly visible like a mobile phone. This ensures the security of the “UMPP Premium” Bluetooth® network.Telephone Switch on visibility? Yes No Telephone VW UMPP PREM visible for 3 minutesS422_042S422_041S422_044The “UMPP Premium” is automatically set to visible when you start Bluetooth® pairing. The manual visibility setting is available in the menu only as an additional option.20Initial pairing via Bluetooth®When you pair a mobile phone, a passkey is transferred that authenticates the devices on the UMPP. This means that the mobile phone checks whether the device that is attempting to log onto the UMPP network is authorised to do so. The passkey is generated by the UMPP and displayed in the dash panel insert (Premium). The pairing process between the mobile phone and telephone preparation can take up to three minutes. The personal identification number (PIN) needs to be transferred to the UMPP if the UMPP is to assume the role of the paired mobile phone in the mobile communications network (only concerns “UMPP Premium”). In the following section, we will explain the initial pairing of the “UMPP Standard” and “UMPP Premium” using the Nokia 3109 as an example.Pairing with the “UMPP Standard”Hardware requirements Working radio or radio/navigation system Correctly installed mobile phone preparation with base plate Bluetooth®-compatible adapter set or universal pairing adapter fitted Bluetooth® mobile phone switched on If necessary, further compatible devices, for example, a headset, (max. seven devices in a network) Software requirements All devices being paired are Bluetooth®compatible The mobile phone needs to support at least the HFP profile and other profiles, if needed, e.g. A2DPBefore you start Click the compatible adapter set or universal pairing adapter into the base plate Switch on and unlock the mobile phone Turn on the ignition and wait around 10 seconds The vehicle is stationaryPairing mobile phone via Bluetooth®Bluetooth S422_046 BluetoothSearch for audio accessoriesActive devicesSearch for audio Searching for devicesStart the search for nearby Bluetooth® devices on the mobile phone by selecting “Search for audio enhancements” from the “Bluetooth” menu.

Confirm the entry with “OK”. The mobile phone saves the Bluetooth® device identification number (ID). The UMPP also saves it in a list for future Bluetooth® connections with this mobile phone. When you turn on the ignition, the UMPP automatically searches for the mobile phone that it was most recently paired with. If this is not available, the UMPP works through the list of previously paired devices in reverse order.PasskeyEnter passkey:****OKDelete S422_051Devices foundVW UMPP Paired with VW UMPPS422_04722Devices foundVW UMPP Allow automatic set-up of connection by the device?Devices foundYesVW UMPP If you select ‘Yes’, connections will be madeDepending on the mobile phone, you can select the option that the passkey does not need to be entered again when the Bluetooth® connection is resumed in future. The connection is then made automatically when the ignition is switched on and as long as the mobile phone is within the reception range of the Bluetooth® network. After the mobile phone connects to the UMPP, it will ask you whether the connection should be set up automatically in future. If you reply “Yes”, you do not have to confirm the selection with the OK button on the mobile phone. If you select “No”, you will need to confirm this by pressing the OK button.Devices foundVW UMPP automatically and without confirmation.

If you complete the entry within this time, the mobile phone display will show that the connection to the “UMPP Premium” has been set up. Similar to pairing with the “UMPP Standard”, you can also specify whether connections should be set up automatically in future whenever the mobile phone enters the range of the active UMPP. After you turn the ignition on, the “UMPP Premium” will try to connect to the three devices that it was last paired with if they are available.PasskeyEnter passkey:VW UMPP PREM Paired with VW UMPP PREMS422_047External SIM accessCancel S422_058The “UMPP Premium” imports the address book from the SIM card in the mobile phone as well as the telephone memory and stores the data in its own memory. This needs to be selected by the user on the UMPP. The mobile phone informs you about this with the message “External SIM access”. This procedure takes place automatically each time a connection is set up between the mobile and UMPP. A maximum of three telephone books can be managed independently of each other by the UMPP.25Using Bluetooth®The “UMPP Premium” allows you to create user profiles for the devices connected via Bluetooth®. You start this by selecting “New user” from the telephone menu. The user profile assigns a user name to the logged on Bluetooth® device that is stored together with the passkey used for the connection. All devices that have been paired with the “UMPP Premium” and for which a profile has been saved are listed in the “Users” menu. This allows a Bluetooth® device to also be connected to the UMPP if, for example, the option for automatic connection set-up is disabled.Telephone Bluetooth Settings BackS422_041Telephone Users New UserTo create and save a new user profile, select “Create User Profile” under “New User” in the telephone menu.

It takes over the function of the mobile phone, which switches to sleep mode while it is being used in the car. The mobile phone performs only monitoring functions in this mode. The mobile phone logs out of the mobile communications network initially while the functions are taken over by the UMPP. Only then can the UMPP log onto the mobile communications network again with the data from the SIM card in place of the mobile phone since it is not technically possible to log onto the GSM network twice with the same SIM identification.Mobile phones without Bluetooth® are not supported by the “Premium” mobile phone preparation even if they are inserted in the adapter set. They cannot be used in this device configuration.If you do not switch on the mobile phone until after you have turned on the ignition, the pairing process must be started manually.An entry-level version of the “UMPP Standard” is being prepared for special markets, for example, South America, South Africa and the Baltic States, for vehicles from MY2010. This UMPP will not have an external aerial, wiring or base plate. Instead it will have a three-button module with the info button, breakdown button and a button for controlling the Bluetooth® pairing.27Using Bluetooth®Pairing further Bluetooth®-compatible audio devicesBluetooth® hands-free system with MP3 playbackTo use this type of hands-free system, the participating Bluetooth devices need to support the HFP protocol. You can receive, end or also reject calls with this. It is still possible to receive an incoming call in “privacy mode”. The sound is then heard only through the headset, not over the vehicle loudspeakers, so passengers cannot hear the person at the other end. When you use the headset, the connection between the mobile phone and UMPP is interrupted and a Bluetooth® connection is set up between the mobile phone and headset.S422_063Closing Bluetooth® connectionIf a device leaves the transmission and reception range of the Bluetooth® network onto which it is logged, the connection to the UMPP will be closed. The same applies if the ignition is turned off and the ignition key removed or the device paired with the UMPP is switched off. If the passkey was saved in the list of paired devices and you enabled automatic connection in the menu during the initial pairing, there is no need to carry out manual pairing again because the connection will be set up automatically. If the device returns to the reception range or if the ignition or device are switched on again, the device will need to log onto the UMPP Bluetooth® network again in an additional pairing process if “Automatic connection set-up” has not been enabled.28ServiceCustomer supportCustomers who already have a mobile phone expect that customer support will explain to them whether and to what extent their mobile phone can be operated via the vehicle UMPP. The schematic diagram on the next double page shows you one possible way of providing the information that the customer needs.Questions that you have to clarify1. What kind of mobile phone does the customer have? Not all customers use mobile phones from the Volkswagen accessories range. To clarify whether and to what extent the customer’s mobile phone can be connected to the vehicle telephone preparation, various information on the mobile phone needs to be taken into consideration (Bluetooth® function, supported profiles: rSAP, HFP, A2DP, ...). If necessary, consult the manufacturer’s pages on the Internet if your customer does not have the required information to hand. 2. Is the vehicle equipped with a mobile telephone preparation and, if so, which one? “UMPP Standard” and “UMPP Premium” basically differ in the possibilities to connect mobile phones to them.3. How old is the vehicle? It is not only the UMPP that decides whether and how a mobile phone can be connected to the UMPP, but also the model year of the vehicle. In vehicles produced from week 22/2007, for example, only mobile phones with Bluetooth® function can be connected to the UMPP even if the “UMPP Standard” is fitted.4. Does the vehicle have a cradle that is clicked into the telephone preparation base plate? Is a cradle available for that specific mobile phone? The type of cradle decides whether the customer’s mobile phone can be operated and charged in the cradle and whether it can also be connected to the UMPP without being placed the cradle. It may be possible to set up the connection to the UMPP if the customer has a Bluetooth® mobile phone and a vehicle with the “UMPP Standard” by using the universal pairing adapter. Use the information provided by the Volkswagen accessories service for these questions.29ServiceSchematic diagramSituation: A customer wants to operate a mobile phone using the controls in his vehicle.It is basically possible to operate the mobile under further conditions. A better transmission quality is achieved if a Bluetooth® mobile phone is placed in the proper cradle as this is the only way to connect to the mobile communications network via the vehicle’s external GSM aerial (only concerns “UMPP Standard”).

AAC (Advanced Audio Coding) AAC is an audio data compression method developed by the Moving Picture Experts Group that is used in the MPEG-2 standard (MP2). ACL (Asynchronous Connectionless) ACL is a data protocol that is used for transferring music, for example. The data are divided into data packets and transferred asynchronously. All data packets therefore have to be received and reassembled as a whole again before playback can be started. PBAP (Phone Book Access Profile) Profile for transferring electronic business cards from the telephone book in the mobile phone to a paired device. ELECTROMAGNETIC SPECTRUM The electromagnetic spectrum is the range of all radiation types that are considered to be electromagnetic waves or their particle radiation. We are surrounded by electromagnetic radiation in all areas of life. The spectrum covers an enormous frequency range from very low energy radiation at a few hertz and wavelengths of several 10,000km to extremely high energy radiation in the zetahertz range with wavelengths of a few billionths of a metre (femtometre, 10-15 m). Examples of electromagnetic radiation include, for example, visible light, heat radiation, X-ray, radio waves, cosmic background radiation etc. GSM (Global System for Mobile Communication) GSM is an international standard for fully digital mobile telecommunications networks. It is the most widespread mobile communications standard in the world and forms the basis for the D and E networks in Germany.
