Not sure whether topost this under the 'problems & fixes' section or here...

So last night, as I was in my car...the navigation screen went black and then a green bar along the top came up and said 'downloading software'. Once that was done, it asked for my pin code. I typed it in, then the map showed, but I was unable to do anything. Then the screen rebooted again and asked for the pin code again...over and over again. The navigation buttons such as 'menu' 'map' 'setup', etc are inoperable. Also I can't switch over to the audio screen, although there is music playing and I can swith stations with the buttons. So as I drive it just reboots and asks me for my pin code.

I'm trying my best to describe this problem. Hoping that others have dealt with this issue and know of any solution. I did make an appointment with the Acura dealership for Tuesday, which I didn;t want to do but I have no other choice!

Thanks in advance!
