Hi all! I just started having an issue where all audio sources seem to be disabled. The vehicle is a '17 Premium w/ nav and Bose, electrically stock. Sunday everything worked, Monday morning, nada. There doesn't seem to be a whole lot of info regarding this specific scenario, but the symptoms are identical to the vehicle in this thread. There was never any follow-up in that thread, but the basic conclusion seemed to be that the AV control unit or wiring had failed. My navigation and backup cam work so I think DCU is out of the question. I took the console apart to get the part number for my unit since there are several different variants. I didn't have my meter on me to probe power but I did check the kick panel fuses, I tried pressing the power button as if it were powered off, I tried holding it down for the reset and I disconnected the battery overnight to no avail. I'm pretty sure this is a hardware problem.
Here is my question, I know that the DCU can get flashed to match options, but is that the case with the AVCU? As long as I get a matching part number I should be be able to drop the new one in assuming it's not harness related issue?
