PCM3.1 unable to select audio source - interface stuck on radio FM, no sound
Good day,
After a massive rain while having clogged sunroof drains I found water in the spare wheel well. Cleaned all drains, removed water and next day morning found that my PCM3.1 is stuck on radio, unable to select another audio source. Can't change volume as well.
The only sound that still makes is the parking sensors warnings.
I did a software reset (press info button for 10 secs, then PCM reset -> vehicle handover reset), removed fuse 51 from right side fuse box for few minutes, removed the battery main negative terminal for few minutes. Nothing works, same issue ongoing.
Any idea where to start looking?
Thanks in advance for your time and support!
