I have an 04 E46 with navigation. I am running the latest update. Every couple of times I start my car I do not get a sattelite sync. When I go into the sensors menu it says GPS Malfunction.

What would be causing this? I can shutoff the car and let the unit power down and then start it back up and it may or may not work again. This is happening more and more.

I think it's version 4-1/80

BTW: Would something like this be covered under CPO, as the orig warranty has expired.

Any ideas?
