GPS device maker TomTom plans to make a mapping unit which would be the heart of a larger ecosystem, according to an FCC filing. Dubbed the TomTom DUO, the handheld would have support for a unique USB docking station in the style of a car stereo's faceplate, allowing direct control of iPods through its touchscreen and routing the audio of any portable audio device through the car's main speakers. Bluetooth and FM transmitters would help eliminate cabling in the link between the car, DUO, and Bluetooth-equipped cellphones, the leak revealed. Exact technical details remain a mystery, but should be revealed by next month's CeBIT expo in Germany, which begins March 15th. Click through for photos. [via Engadget and GPS Review]
