I have '06 MDX Touring w/ NAV & RES and I am not getting any sound out of the speakers. The radio/CD, etc work as I can hear them thru the wireless headsets. I actually replaced the radio with one that I know works and I have the same issue. The interesting thing is that they starting working couple of times (briefly) the first time it happen and then they haven't worked since. I've looked at the wiring out of the back of the radio looking for a broken or shorted wire, but didn't find anything. Any help/ideas would be greatly appreciated! Thanks in advance!

 

I think senor module must be out of alignment either for the brake or accelerator. It is located somewhere around the upper arm of both, you must try adjusting them. It may help you.
