When we bought our Camelot several years ago, it came with a Kenwood radio, with a flip-out DVD player & screen. Waaay too many buttons for me to figure out, especially while driving. I did learn how to get FM and GPS functions, tho. I even found where the PO lived, by using the "Home" button on GPS 😀 .
Anyways, you might check into the Kenwood line, they seem to be very versatile.
