I know it has something to do with the MOST bus. From what I've found online, if it's disconnected, or the moduel it's connected to stopped working, it will cause the same issues i'm experiencing. No sound no cd/dvd playback, no nav, and other issues. Also CIC might be looking for whatever option it had before, read that coding can disable the option so the MOST bus can stop looking for it. Unfortunately, I can't do that without instructions and the proper program/tools needed. Found some good info, but nothing soild. 2 days in and no luck. This is really frustrating. Where the hell do the Most wires in front go ? I need to find where they go to see if there is a break in the connections.
