my friend got a s13 that came with the TV - navigation setup, he has never used it because of the cost involved, he said it's not worth it and too hard to source parts cauz it's from japan. the only thing he said it's good for is hooking up a portable dvd player he got which reads ntsc onto to the aux connections, and trying to find ntsc or multi zone format dvd's. but dont chuck them, hang on to it, u jus might find a way one day....
