i have an 04 escalade ext. does anyone know how i can bypass the nav system so i can use it while moving?? i know my friends xlr has a code screen where you just enter an override code into the headunit and it will allow the video to work without the parking brake but even he hasnt found the code to get the nav to work.

is there anyway to get mine to work??

It would be nice to be able to use it in the Hummer too while driving. Well not the driver.

im really trying to find a way to use my nav while driving.. it sucks!
