  1. 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.
