Bluetooth, MP3 USB, AUX input, interface adapter for NTG 1, NTG 2, Audio 20, APS 50 and Comand Mercedes-Benz radios

Digital Music Changer LP1603MBZ8 ( 8th generation with latest firmware! ) is an interface / audio adapter for a number of factory Mercedes-Benz car radios with a MOST optic fiber system (fiber optic).

This interface makes it possible to play music in MP3 and WMA format from a USB stick or a microSD card in CD quality via your car radio. The interface also has a 3.5mm AUX input / audio connection for external sound sources and an integrated Bluetooth module with which music can be streamed wirelessly and hands-free calling can be made.

This interface / audio adapter behaves like a CD changer and is also recognized as such by your car radio. This maintains the full functionality of your car. The interface is operated simply via the buttons on your steering wheel or via those on your car radio. CD and track numbers are shown on the display of your car radio.

The integrated Bluetooth module makes it possible to make hands-free telephone calls and to stream music wirelessly from a mobile phone or other connected Bluetooth device.

Comments:

• Comand NTG2.5 is not supported! This has an SD card slot on top of the device's screen.
  
• If there is no external 6-disc CD changer or OEM telephone module or external amplifier with navi box, then in most cases the CD changer support must be enabled (coded) via OBD by the Mercedes dealer.
• Audio20 car radios without a factory-installed CD changer are not suitable. CD changer support can be enabled with a diagnostic computer, but that makes the radio not compatible with this interface.
  
• Cannot be combined with an existing CD changer. Existing CD changer must be completely disconnected. If there is a CD changer in the trunk (only applies to S, SL, CL class), an optical loop / bypass must be placed on the MOST connector of the disconnected CD changer. This is included.
