E70 Audio Systems Workbook 3 4 E70 Audio Systems Workbook Audio Systems The US vehicles are equipped with the new head unit platform called CHAM P (Central Head unit and M ultimedia Platform)The CCC (Car Communication Computer) is available as the head unit forthe Professional navigation system. The head units offer eight favorites buttons. Professional Radio (CHAMP) The CHAM P and CCC have eightfavorite buttons, six assignable favorites buttons. Button 7 is assigned with FM/AM selection, but¬ ton 8 is fortoggling the operating mode. CHAM P combines the following control modules in the one housing: • RDS double tuner • Audio system controller • Gateway between MOST and K-CAN • Interface to the Central Information Display. CHAM P system can be used to control: • Communication • Entertainment • Air conditioning (climate control) Professional Radio with NAV (CCC) Note: Button 7 is assigned with FM/AM selection, button 8 is fortoggling the operating mode The CCC combines the following control modules in one housing: • Navigation computer/GPS module; map view and/or cursor view in the CID • RDS double tuner • Audio system controller • Gateway between MOST and K-CAN • Interface to control display (LVDS). Two drives are integrated in the housing: • DVD player • CD player When the navigation system is not in use, its DVD drive can be used to play audio CDs.The playback of video files is not support¬ ed.! he system can be used to control: • Communication • Entertainment • Navigation • Air conditioning (climate control) • Settings (5th menu).The MP3 directory structure corresponds to that of a PC. There is no limit to the number of directories, sub-directories and music tracks that the CCC can support. However, the time taken for the drive to read the contents of the CD when the CD is inserted is longer, depending on how much data is stored on the CD. Amplifiers and Speakers The speaker systems in the E70 are, as in other Series, available in two quality levels: • HiFi system • Top-HiFi system. Even though the diameters of the speakers in the HiFi and Top- H iF i systems are the same, there are differences in the power out¬ put of the speakers. This is achieved through the use of different materials in the diaphragms, coils and magnets. The HiFi system achieves double the power of the standard stereo system. In addition, the HiFi system is equipped with a 7-channel amplifier with digital equalizer. The optional Top-HiFi system achieves double the powerofthe standard HiFi system and uses a digital 9-channel amplifier. Optimum audio playback in the vehicle is achieved thanks to com¬ plex digital signal processing. The HiFi system has twelve speakers, five tweeters, five mid-range and two central bass speakers. The HiFi amplifier is woken by the Rad_On signal sent by hard wire from the Head unit and uses a K-C AN connection for diagnostics and coding. TheTop-HiFi system has 16 speakers, seven tweeters, seven mid¬ range speakers and two central bass speakers.TheTop-HiFi ampli¬ fier is connected to the M 0ST. The central bass speakers are located underthe front seats. They are coupled to the side sills to increase the resonance volume nec¬ essary for bass reproduction. The CHAM P and the CCC (navigation system) can be combined with any ofthe amplifier/speaker systems, provided the specific national variants are taken into consideration. Note: CHAMP receives the terminal 58g (lighting) signal via hard wire.The CCC receives it via the K-CAN.

E70 Audio Systems Workbook 13 14 E70 Audio Systems Workbook CD Changer The new 6-disc CD changer (CDC) is available forthe E70.The first time that a single-slot CD changer has been fitted in a BMW vehicle. It is manufactured by Alpine. The CD changer is located behind the glove box and it is integrated on the M OST network. Single-slot CD changer means that the CDs are loaded individually into the device without a magazine. A CD can be loaded by press¬ ing the load button, followed by the button forthe operating tray of the CD to be inserted. If no button is pressed afterthe load button has been tapped, the LED in the operating tray button assigned to the first free tray flashes. In the meantime, the tray moves into posi¬ tion. When the tray is in the correct position, the status display begins to flash and the CD can be loaded. The contents of the CD are read as soon as the CD is inserted. The next CD cannot be inserted until the contents of this CD have been read. The rapid loading fea¬ ture must be activated to be able to insert all CDs immediately one afterthe other. To do this, the load button must be pressed for approximately 2 seconds. The LEDs in the operating buttons assigned to free trays begin to flash. Up to 6 CDs can be inserted one afterthe other, depending on the number of trays free. The contents of the CDs inserted are read either once the final free tray has been filled, on expiry of a time out or if the load or eject button is pressed. An individual CD can be ejected by pressing the eject button followed by the operating button concerned. Pressing and holding the eject button ejects all the CDs. The CDs cannot be loaded unless the shutter is open. The status display flashes when it is possible to insert a disc. Operation is described in detail in the Owner's Handbook forthe vehicle. CD Changer Location Note: If the eject button is no longer working, a CD can be ejected using the diagnostic tester. If the C D is mechanically jammed in the drive, it is necessary to send in the CD changer. The CD changersupports the following compressed file formats: • MPEG-1 Layer3 Audio (MP3) with ID3 tag version 1 and ver¬ sion 2 • Windows M edia Audio (WM A) with WM A tags • Advanced Audio Coding (AAC). The data on the CD is decoded by the CD changer and converted into the digital MOST format. With the HiFi System, the digital data on the CD is sent to the head unit via the M OST, where it is then converted to analogue data and output via the amplifier and the speakers. If the Top-HiFi system is installed, the decoded audio data is sent directly to theTop- HiFi amplifier via the MOST from where it is output.This direct transmission bypassing the head unit is made possible because data conversion and sound adjustment take place exclusively in the Top-HiFi amplifier. Retrofitting a C D C hanger The fiber optics conductors forconnecting the CD changer are arranged at the fiber optics connector in the luggage compartment such that they are not incorporated in the MOST ring. After retro¬ fitting a CD changer, the fiber optics conductors forthe CD chang¬ er preparation are unplugged at the fiber optics connector and con¬ nected to the MOST ring. It is then necessary to code the entire vehicle. Note: For more information referto the technical training material on available onTIS.

Because of the arrangement of the orbits, there are always two satellites over the reception area.In areas with¬ out coverage, the SDARS signals are beamed terrestrially. Both SDARS signals (satellite and terrestrial) are received by an antenna patch in the roof antenna and made available to the SDARS control module. Note: The antenna inputto SDARS uses only one connec¬ tion forthe Satellite and the Terrestrial antenna.

E70 Audio Systems Workbook 17 18 E70 Audio Systems Workbook Rear Seat Entertainment (RS E) A rear entertainment system" Rear DVD system" is offered as an option in the new BMW X5 (E70).The system consists of the fol¬ lowing components: • Rear Seat Entertainment (RSE) control module • 8" color monitor with folding mechanism and infrared transmitter • Headphone connection • Remote control. The "DVD system in the rear" offers the following functions: The rear seat entertainment is functionally independent of the other entertainment sources available in the vehicle. Via the iDrive, the driver orfront passenger can release or lock the rear seat enter¬ tainment in the "Settings" menu. The rear seat entertainment pro¬ gram cannot be controlled by iDrive. Once the rear seat entertainment system is activated, the rear-seat passengers can be entertained by the rear display and headphones or audio speakers in the vehicle. If headphones are used, a different medium can be enjoyed via the rear seat entertainment system, independently from the vehicle audio system. The rear seat enter¬ tainment display or headphones can be controlled by a remote control. The settings made are displayed in the rear display. No visual status signal display is issued forvolume navigation.

The test plan works through the following steps: • The entry of the current detected remote control forthe rear seat entertainment is deleted in CAS3. • The remote control forthe rear seat entertainment is initial¬ ized. • Successful initialization of the remote control is acknowledged bythe automatic closing and opening ofthe central locking. Note: Remote controls are not interchangeable. Only the initialized remote control is functional in the vehicle.
