Summary: Very good device for my bike! Just buy it + touratech mount and all the roads are open! Similar in features to its predecessors in the 2000 series, including the 2720 and 2730, the 2820 adds the capability of bluetooth cell phone connection that allows for 'hands free' phone calls through the unit.
Summary: Has it all at a very good price. Need to keep map data current to be useful. When buying opne used make sure you ask if the unit can be re-registered by you as the new owner. If not then beware. Could be stolen.
Summary: I like the fact it is bluetooth capable and the maps are pre-loaded so there are no memory cards to fool with. I upgraded to the 2820 from a 2160. I used it on mu motorcycle as well as the car.
