I am posting the following because of a recent series of posts by new members that really have nothing to do with audio or telematics, and that would have gotten more timely responses if they had been posted in the vehicle-specific forum.
What does this forum encompass? The audio portion is simple: Anything attached to your car's audio system, including COMAND and AudioXX head units, CD changers, telephone systems, USB and smartcard readers, amplifiers, Tel-Aid and MBRACE systems, Sirius receivers, and of course, navigation systems - including 3rd party, if we can help. It encompasses Telematics - that is, telecommunications, sensors, instrumentation, wireless communications, etc., and computer science (multimedia, Internet, etc.) applicable to our cars as they relate to road or vehicular safety.
It does NOT encompass a malfunctioning item that just happens to be electrical - i.e., a window switch, dashboard switch, blown fuse, the electronic control units for a particular subsystem (e.g., door control unit, ECU, ABC, Airmatic controls). Those questions are better suited to the forum for the specific kind of vehicle, where more members may be directly familiar with such issues.
Because our experience in 3rd party audio and navigation systems may be limited, we would appreciate your posting your experience, and also cross-linking to helpful articles on installing such systems in our Mercedes automobiles.
If you need information concerning repair of Mercedes electronic components (whether part of the audio or telematics systems or not), please see the sticky at https://www.benzworld.org/forums/aud...ectronics.html
