Nav Radio issues?

[giant h2]

Hello gang happy peaster!!

Hummers great, 125k miles now.........

My wife recently had an interesting issue. She told me her nav radio would not turn on for a few days, also no back up cam. On the third day the car would not start. Called AAA they charged the battery, check it and the alternator both ok! Radio works again but now seems to reboot itself while on? Goes to the H2 screen like at start up?

Anyone have any ideas??

Oh its a 2005 H2

Yikes...I hate those weird problems. What are you/wifey typically doing when it reboots? Is there any common factor? Like does it only happen when you listening to XM, or when you're on a bumpy road, or when you turn left, or is it completely random?

Hmmm...I'm thinking maybe a faulty NAV. I had two factory Delphi NAVs go bad in my 05. Not with the symptoms that you're describing, but still...

...I wish I had more for you, but that's my initial thoughts.

I know there is a software update for various problems with the nav radios. Requires dealer to upload new software with an update.
