it drives me nuts - I don't want to have a tiny-screen garmin and the GM mapping going at the same time... one of these days, I'll find the converter to make my Nat Geo maps work on my Hummer... although, it may take getting a different stereo that is compatible with outside mapping software.
I mean, really, an off-road vehicle that you can load off-road maps onto the SatNav.... stupid, stupid, stupid, stupid.
oh yeah, and there's no way on God's green earth that I'm spending 200 for 3 year old mapping software.:whaa:
