2. Channels: The more channel  you get, the better reception you can have.

5. What kind of company (brande name) that makes the GPS receiver? You don't want some no name companies making GPS receiver and getting terrible reception whenever you are urgently in need of the location. Company such as EMTAC has been manufacturing GPS receiver for years, and they are one of the pioneer introducing the Bluetooth GPS Receiver.
