Street Pilot 2660

Product description from Garmin:

Driving in areas where a GPS signal is intermittent—such as intense urban environments with tall buildings or mountainous terrain? The StreetPilot 2660 has all the features of the 2620—including pre-loaded map coverage—in addition to dead reckoning. This means that once the unit is installed by an authorized Garmin installer, you'll continue to get navigation guidance even if you lose GPS reception.

The StreetPilot 2660 is a plug-and-play portable automotive GPS navigator that features MapSource City Navigator pre-loaded, detailed maps—right out of the box. This means no unlocking or uploading map data to your unit! Its pre-programmed hard drive stores City Navigator maps of North America or Europe (see "Package includes", left). Motorists can navigate to a specific address or access an industry-leading database of more than five million points of interest—including lodging, restaurants, gas stations, and local attractions. The intuitive, menu-driven touchscreen ensures that navigating the unit is as easy as navigating the road.

This unit also features a high-resolution color touchscreen with voice prompted turn-by-turn navigation and a powerful microprocessor for fast route calculation and map redraw. The system includes a unique wireless infrared remote control, which allows easy operation of the unit from a distance. The StreetPilot 2660 also offers WAAS-enabled support to ensure the highest degree of GPS accuracy.

Unlike the 2620, the StreetPilot 2660 has dead reckoning capabilities, so you’ll continue to get navigation guidance even when GPS signals are obscured. To use this feature, a special dead reckoning cable must be connected to your vehicle's speedometer and backup lights by an authorized Garmin installer. Once installed, your StreetPilot will acknowledge your turns as well as your distance traveled when GPS reception is unavailable. Driving with dead reckoning capabilities is so seamless, you won't even know if you've lost GPS reception.

Simply unplug the dead reckoning cable from the vehicle adapter if you want to use the 2660 in another vehicle. It will navigate the same way as the StreetPilot 2620.
