I purchased displayout last night and I have the Apple av cables. Here is what I want do do, but I think its impossible. My car (Pontiac G8) has a built in screen for the radio/hvac. I just bought the panhlldr mount because I already have the dash mount and I dont want to do any customizing. Here is my question. Lets say I have navigation going on the Ipad screen. Can I display a different app on my cars screen? I seen you could do it on a mac/pc, but I couldnt find what I was looking for.
