I ran across the TravelPilot Rome Nav55E in the Blaupunkt booth at the Geneva Auto Show. It's a single-DIN stereo head unit with integrated GPS navigation. Because of its small screen size, navigation is limited to route guidance; you won't be studying maps on this thing. Also, destination entry covers only points of interest and city centers. The interface is too limited for full address entry. As for the stereo system, it has the usual tuner and CD player, capable of reading MP3s and WMAs.
