Maybe having that unit down there is NOT a problem, I looked at it today when driving my Hummer. You don't really need to push a lot of buttons on GPS as stereo, especially if it is voice activated.
I cannot find any excuses to buy GPS or any LCD screen, as much as I like them as toys. 18 minutes to office, 5 minutes to school, no long road trip and not yet a need to find direction in years.
HeeHaw, did you get hold of that guy
eric@hummerh2.org? everything works out OK?
