Just got my car back from the shop and I am not getting any audio (from radio, CD, Tape, DVD or from display buttons that normally beep). Only sound I am getting is from seatbelt warning.


The shop just serviced my drain lines from my sunroof....they were clogged and getting water onto my floorboards. The sound was all ok prior to this. Shop said there should be no impact from what they did.


I checked both audio fuses and they are fine ( #20 and #55).


From other threads, seems a likely culprit might be the amp. I can't seem to find any loose wires or connectors.


The questions I have are:


1) Is there anything else I should check other than the amp?


2) For my model/yr, is the amp and navigation CD player one and the same unit? (under the front passenger seat)


3) Is there a way for me to test the amp? It seems to be a bit expensive so I want to be sure that's really the problem.


Thanks in advance for any help.

Update: I took it to an audio shop and they say that the amp is back. On my model it seems the amp is in the dash behind the radio, not under either of the front seats. The recommended that I NOT go the aftermarket route...based on their experience. They said I should either buy one from the dealer (ouch)...or search used auto parts for one in good shape.
Any inputs are welcome at this point
