TomTom this morning changed its usual formula with the launch of an installable in-dash GPS unit. The GO I-90 occupies two DIN slots in any car and provides a large touchscreen with both TomTom's staple GPS as well as media features the company normally has no reason to use. Owners of iPods can plug the Apple devices into a USB port to both play and charge their devices; the unit also has generic MP3 player support and its own FM radio tuner.
