EDGE GMT

I'VE TRIED THE PORTABLE DVD. DID NOT CARE FOR THEM. (KEEP FALLING OFF STEERING WHEEL) .THATS WHY I,M DRIVING A EDGE INSTEAD OFF MY F-150 SUPERCREW.

HAS ANYONE INSTALLED HEADREST DVD PLAYER OTHER THAN THE $1200-1800 DOLLAR ONES. ARE THE $400 WORTH ANYTHING ? WILL USE ONLY A COUPLE TIMES AYEAR.
