We replaced the standard Ford double-DIN (4 inches high) radio in our 2007 E350 rig
with a Kenwood DNX9960 radio with GPS, based upon advice from a couple of fellow
Forum members. We get the ability to play our CDs, our iPods, etc. The DNX has a
7-inch screen that covers its whole front face.
As a bonus, we were able to hook up (with the help of a *really bright* local technician)
the back-up camera display to the DNX, so the rear view appears in the dash. No more
head-bumps on that screen dangling from the cockpit ceiling!
I'm very pleased with the results.
