New Tahoe Navigation freeze

Just got a new Hoe and the navigation would freeze here and there. It would freeze for lengths of time and I wouldn't be able to do anything with it. Anybody else have an issue like this? Is there a way to reset it while driving? Or anybody else experience issues like this? What's the fix?

Hmmm haven't heard that one, maybe some kind of firmware up date is needed.

sorry this was meant for the other section. This is a 08 tahoe so the firmware should already be updated. I am going to repost in the other section.
