saw this s430 online..its for sale in florida . anyways it has the factory command screen with dvd playing on it! theres an aftermarket unit in the glove box.. check out these pics. maybe someone can figure out how this works! it would be awesome to know. here are the pictures.

 

That does seem to be a U.S. specification unit. I don't know who did this particular modification, but Nav-TV used to do them if you sent your COMAND unit to them.

 

ohh i want that anyone still doing it

 

thanks skylaw! and tusabe i went on nav tvs website ...the interface cost around $650.00 , and according to them its pretty much plug and play .
