In my last Farctic Ox, I swapped out the stereo for one with DVD. I went with a Kenwood DNX5140.
Now - worth noting
If you do go the route of changing the headunit, by law, all car-stereo head units have to have a "No DVD while driving" safety feature. All are bypassable of course, it's just how much of a PITA it is to bypass it.
Most involve connecting a wire to the E-Brake switch, which means you can just ground said safety wire and you're good to go. Others, like Alpine, are an ABSOLUTE PITA to get working in this situation.
Moral of the story - If you go this route, make sure you read the directions and make sure you understand how to bypass the DVD-safety so you can use it in your TC.
