Was wondering how you made out the 2013 NAV upgrade disk ..worth it..??naylor99 said:Just did mine, but haven't driven it anywhere to notice a difference as of yet. Plan to do it on a highway trip, though - takes about 80 minutes total to run through 2 DVDs for installation! And if you stop, you have to start over. Kind of a ridiculous amount of time, but I assume it is a lot of new data? time will tell!

On my 2008 Avalanche I had a "change" option under NAV that opened the radio. I don't see that option on the 2013. Called GM and they said touch Menu-NAV-Data Base Info, but that doesn't open it. -- Ted
