I finally did it... I #@%^#@ blew up the audio comming from the OEM system (before OEM AMP)!. Not a good idea about getting an old aftermarket amp from craiglist :-). It appears the aftermarket amp shorted the amp out with one of the audio inputs (comming from the OEM system). A nice barbacure smell came from two parts if I am correct.
One from the CCC or head unit (or close to it) and saw smoke coming out close to the OEM AMP (OEM AMP can't be as it was totally disconnected - whole plug out).

The computer works, navigator, CD, etc. just no audio even if connected back to the OEM AMP or the good/new AMP. The speakers are fine - tested with an IPOD connected into the Aftermarket amp). I think the output stage of the pre-amp went ballistics. Thing is, where is the pre-amp?

Now, in a "normal" car, the problem will be the Head Unit; but in the BMW I don't know if the head unit/CCC is the "concentrator -audio from navigator/BT/Radio/Bells" or there is another box in the chain between the radio and the oem amp.

Any ideas?

The OEM headu unit is available as a replacement $1,400 or in ebay for $200 ~ $500
