Which Amp came from factory?
Hello everyone,
Can someone tell me which Harman Kardon Amp was installed in my S Class from the factory?
I recently bought this car and assumed a defective amplifier, but there was no one installed.
Unfortunately I don't have access to the ETK.
My chassis number: WDD2210711A031259
Would be nice if someone can tell me which part number I can use or if they are all interchangeable.
Thanks very much

I posted what MBUSA EPC shows pulling your model. 7789 & 8103 are compatible, 8004 (-810) is not. Any previous #s that 7789 actually replaced should be compatible.

the older the number the older the part and thus more likely broken (second-hand)
the later ones would have a later version of the software inside (mid 2010 they had a flash of a later iteration) - on some other merc models it was to try and help reception - not sure how that would work - it would still operate but what ever fun they were fixing obviously wouldn't be there
