Garmin Street Pilot 2820MSRP: $1075M
Sure, it's pricey, but this is one feature-rich motorcycle navigation tool. Highlights include a high-resolution color touch screen, usB port, 128mB flash memory (included), 12-volt and 110-volt power adapters, remote control, two mounting systems, detailed downloadable maps and a large menu of adjustable capabilities. the internal software is on par with many auto GPs systems, and the processor speed's wicked-fast. New features include automatic zoom-ins of complicated intersections and route prompts with adjustable "biases" (for when you're walking versus riding, and so on). the 2820 adds Bluetooth technology for wireless integration, and Xm satellite weather info includes forecasts and current conditions. ou can also transfer the unit between your car/boat/motorcycle with ease. For $100 less, the 2720 omits the Bluetooth.
