I recently installed an aftermarket NAV/DVD unit in my 08 Edge SEL. I hadn't noticed it before as this is my wife's car but the driver's window & vista roof don't work at all also, there is a "no communication with compass " notice on the dash now. I tried subbing the old radio back in but all 3 problems persist. Did I disconnect some "main" wire? Everything looks fine. HELP !!

I recently purchased a dvd/nav unit and want to install it in my 08 EDGE. Is there a "magic" adapter wiring harness that will interface all the Edge wiring to this unit. Most all of these dbl din units are pretty much the same the way they are set up.... its just connecting all the spaghetti correctly that slows me down.....
