My head unit freezed again yesterday.
Only the GREAT "PORSCHE" letters are displayed.
I had complaints it three times now to dealership. The last time, I thought they fixed it, but NO. Anyone experiencing this???

I cruised without a single song yesterday. Frustating.

 

Happened to me a couple of times. My fix was to shut the car for 10 seconds and start it, that seemed to fix the problem.

 

Just do what Jamy said. Happens to me at least once a month in both of my cars. Very frustrating at times but it's got to do with the MOST bus so very little can be done to get rid of it.

 

I thought I am alone.
10 secs then. I will try it.

 

You're certainly not alone. Infact, I don't ,personally, know anyone who has a MOST bus equipped car that didn't experience this.

 

I had the same problem with the PCM2 in my carrera. I fixed it by zip strapping the fiberoptic cable to the wiring bundle. My guess is sometimes it kinks and causes this...
