It is with great pleasure that I would like to annouce that Porsche has fixed my issue with the Bose SURROUND setting not staying enabled. I took it in to the dealer about 3 weeks ago and there was a campaign on my PCM. For the last three week I have observed the suurround setting and it has stayed enable. Whatever they did in that PCM update fixed the problem. Home this help so me of you.
It is job #3. The other ones do not have anything to do with the audio setting. I am not 100% certain it is what fixed it but after they reprogrammed it, it seems to be working and it is going on 4 week with no issue.
