For drivers in congested metropolitan areas, Garmin is offering the GTM 10, an optional FM RDS-TMC traffic receiver that receives digital information (where available) on traffic, road construction, and weather-related tie-ups. The GTM 10 receives data from selected FM broadcast stations in select cities throughout the United States and Europe. This optional feature lets drivers see congested areas via a color-coded map. When connected to the GTM 10, the StreetPilot 2720 uses this data to automatically calculate and suggest alternative routes based on the traffic information.
No XM traffic, but it is cheaper if all you wish is traffic info. otherwise stick with the 376C
