Garmin shows the Street Pilot c330 that competes directly with the TomTom ToGo GPS Gadget. Apparently Garmin already had the Street Pilot in the works, when TomTom stole their thunder and released the ToGo before them.

The StreetPilot "c-series" GPS navigators feature a simple touchscreen interface, with automatic route calculation to any destination and turn-by-turn voice-prompted directions along the way. Selecting a destination is straightforward and requires only a limited amount of input from the user. Plus, the StreetPilot c320 and StreetPilot c330 allow you to choose between a three-dimensional navigation view or the more traditional “bird’s eye” overhead view.
The centerpiece of both units is a bright, 3.5-inch diagonal, 16-bit color display.
Available in March 2005 at an MSRP of $964.20.
