Garmin StreetPilot 2650 Car GPS Receiver

Just choose your destination using StreetPilot's touch screen or remote control to be automatically guided with turn-by-turn directions and voice prompts. Both the 2610 and 2650 feature color displays, built-in maps, and everything needed to download additional map detail and look up points of interest and addresses in seconds. Select maps and transfer data directly to the unit through a USB connection and onto a standard CompactFlash® memory card. These products are powered using the external speaker with 12/24-volt adapter cable or A/C power adapter (both are included in the purchase). The StreetPilot 2650 also has dead reckoning capabilities, so you'll continue to get navigation guidance even if you lose GPS reception, such as in intense urban environments with tall buildings and tunnels. To achieve dead reckoning, the 2650 features an internal angular rate sensor, an external speed sensor input, and an external reverse light sensor input.
