The rest of the world is so far behind... for some reason, Japan is rocking in-car navi/AV. Mugh like that Kenwood link...
My car has a 2-DIN touch screen GPS and AV system... plays CD/DVDs in multiple formats, including MPEG, avi, MP3. There's also an SD reader built in for more movies and music, and a USB thumb drive reader... as well as ipod connector. Does TV too. Oh and Bluetooth - you can link your phone for hands-free operation. GPS is stored on RAM-type memory. Also accesses SmartLink for real-time traffic conditions and accident updates etc. And of course reversing camera.
I bought it 8 years ago. You should see the new ones ones that do AR and have HUDs
