Is there a way to wire up switches so that the trucks nav unit thinks it is in park/ebrake on so you can watch DVDs while driving? I know there are ways to do it on aftermarket screens, but i was wondering if anyone had attempted it on the new chevys and knew which wires to go after. Thanks, Jason

 

I believe its a company call coastaltech, they makea harness that plugs in the back of the factory nav and lets you watch while driving. If I remember correctly its about 250.00 though.

 

Are you kidding?

Don't think it costs more than 10% of that to even make something to interface with a stock radio. I'd be curious to how a $250 harness is a cure-all for the original poster's request.
