I have read several threads on the PCM's, in my case for a 997.1 MY2008, but haven't reallys seen these problems identified:

Sometimes when I turn on the car, the Main screen just shows the orange outline, not the RDS display. If I turn off the PCM, then restart it, everything works. Sometimes, when I am alone in the car, the radio station changes. I also noticed that my #1 station was replaced by my #6 station. Perhaps, the car just hates my music, but maybe a software glitch?

I suspect Bill Gates has a hand in here. Do an engine shut down (reboot) and start again. If that doesn't sort it out start to involve the dealer.

I get some weird glitches too. Like the CD won't change tracks unless I switch to radio then switch back again.

No glitches. Although only once the nav failed to track my
movement.
