Palm's GPS Navigator Car Kit for Treos

Doesn't look like Palm will be busting out any new phones at CTIA, but they did announce a new GPS thingy for Treo 680 and Treo 700p smartphones. The GPS Navigator Car Kit is a GPS attachment designed to cradle your Treo for in-car use. Comes with TomTom NAVIGATOR software and a 1GB SD card preloaded with maps of the US and Canada. Retail price should be $299.
