2007 is350 with 56,000 miles. I just got the car from an auction and the audio doesn't seem to work. When I got to audio controls they don't respond when I press them. Everything works else except there is no audio. What could this be? Where should I start looking? Thanks

 

Touch screen NAV or NO NAV... Need some more info.

 

Touch screen nav.

 

If the touch screen is dead, do a search here...TONS of threads here about a dead touch screen.

 

No, the touch screen works, navigation works, back up camera EVERYTHING works except there is no Audio and the audio controls like the bass don't seem to respond when I touch them. No sound coming out from the speakers.

 

sounds like a dead amp. Was there any aftermarket wiring or equipment left in the vehicle?

 

I had a similar issue a few weeks ago, took it to the dealer and it turned out to be the amp.

 

I don't see any aftermarket wiring. Damn how hard is it to replace the amp? How much did it cost? Thanks

 

It was covered under warranty for me so the dealer did it for free

 

factory amp might cost a pretty penny if it's the mark levinson. I suggest time to upgrade to a proper 5 channel

 

Okay fixed the problem. The car was hit on the quarter panel and the impact crushed the amp. Replaced the amp (got one for $150) and replaced two 30 amp fuses under the hood. Everything works now, thanks.

 

Glad to see you got it resolved without having to fork over too much money
