Radio / CD / Nav display issues

[pdavis1]

The radio / cd / Navigation unit in my 2006 Carrera S is having display issues. I can't figure out a pattern. It is sporadic, happens sometimes when cold, sometimes when hot. Sometimes it is fine a startup and then goes haywire, sometimes the other way around. Is there a fix other than replacing? Is this a common issue?

It always produces something. Sometimes almost solid white lines, it has even done duplicate images side by side at half of their original size.

I also have a random issue with the display screen on my 08 C2S. Sometimes when I start the car the radio will play but the screen is totally black. I've pushed the upper righthand button that will black the screen out and then turn it on and nothing. I've also powered the unit off and on and nothing. Moments later, viola and it will display everything normally. Maybe I should somehow convince my dealer to exchange the unit out before my CPO runs out?

See if you can catching it acting up with the video camera on your cell phone and then show it to your dealer. If you're under CPO they should absolutely replace your PCM.

Good point PTEC. Didn't think of that and the dealer wasn't able to duplicate the issue. I've got five months to catch it in the act again. Thanks...

Phil, these things can go South in a zillion ways. There are thousands of components in there any one of which can fail. They can not be diagnosed and repaired in the field. So, they provide rebuilt units for ridiculous money. If you are stuck in the position of having to pay for a new/old unit compare the cost with that of going to the aftermarket. These guys here know my mantra. With either Alpine or Kenwood you can get a totally modern unit with all the goodies and a custom bezel that even has the Porsche factory finish. The whole thing looks stock. The only kicker is you have to get a NavTV MOST head unit replacement module. This converts the analog output of the aftermarket units into MOST digital for Porsches system. This also allows you to use your stock amps and speakers. The NavTV u it was $699 the last time I checked. Pricey, but way cheaper than replacing the amps and speakers. Way less collateral damage also.
