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. The thing I like best about 2820 is the fact that I can place and receive calls with mu cell phone totally hands free, yes even on the motorcycle via the bikes intercom system and the helmet headsets.
Summary: this GPS is replacing a Street pilot 2610, so it fit the mounting bracket on my motorcycle and the wiring also. it is a better unit than the 2610 was as it has mp3 player and bluetooth for my cell phone. i like the 3d screen and the ease of use. i am very satisfied with this product.
