I HAVE A 2004 ESCALDE. I HAVE INSTALLED A FACTORY 2006 ESCALADE NAV SYSTEM WITH TOUCH SCREEN. I AM TRY TO DEACTIVATE THE "OPERATES ONLY IN PARK" FEATURE. I UNDERSTRAND THERE IS A WIRE IN THE NAV HARNESS THAT CAN BE DISCONNECTED AND THIS WILL FREE THE SYSTEM UP SO IT WILL OPERATE WHILE THE VEHICLE IS IN MOTION. I WAS ABLE TO DISCONNECT THE ODOMETER AT THE MAIN COMPUTER. THIS ENABLED THE NAV SYSTEM TO OPERATE WHILE THE VEHICLEWHILE MOVING, BUT I LOST MY SPEEDO OPERATION. ANY HELP IS APPRECIATED.

I believe "tv and nav 2 go" (do a search on google) has a solution.

 

eric, thanks for the advice. i will give it a try.

I just bought a 04 and would like to go to a touch screen nav. I have seen several on ebay. How difficult was it to swap out? Is there anything that can be done only by a dealer. Thanks.
