Porsche Cayenne PCM system resets by itself
Problems with PCM system
The dealer loaded the new software couple of times and it did not fix the problem. Then they replaced the entire Navigation unit, it improved the situation a lot but did not fix it 100%. After I purchased the new iPhone 5, it seems to work flawlessly. I believe the problem is caused by the Blue Tooth Software in Porsche Navigation system that is not totally compatible with first generation iPhone.Try using it with a new iPhone or a different phone that uses newer version of the Blue Tooth.
10xthe problem is i don’t have any phone paired with pcm device. at me restart itself without phone…

Had the same problem in my 2013 Panamera.. They had to replace the entire head unit
I have had this same problem! It is very annoying. This is definitely my last Porsche purchase.
