I have the Bosche Highline radio in my American 2015 Passion coupe. I had it installed after purchase by the dealer, so it may or may not be the newest possible model of the radio. I have a 64gb SD card (contains nothing but mp3 tracks and jpg album art in Windows format folders) in the SD slot...

I've been using my Dell Notebook for GPS and mp3 playback for a couple years. But, I've been checking out in-car PC solutions lately. Particularly Double Din in dash units. Seems to be a developing market, leaning strongly to the DIY types (barebones systems, and such) Has anyone here...
