It may be easier to use than Microsoft Streets and Trips, but the DeLorme Earthmate GPS BT-20 still has a lot of room for improvement. Connected via USB or Bluetooth, the DeLorme is easier to use because the routing and navigation controls were easier to find. However, the reviewer found the interface quite cumbersome and quite difficult to use. Instead of being able to automatically route to a place, extra keystrokes are needed to send it to the “routing tab” before you can proceed. Also, the GPS receiver doesn’t track positions as often as a standalone navigator does. The reviewer stated that during testing, 2 minutes went by without a position update. Though it does offer street name pronunciation and easy rerouting, “unnamed roads” still crop up every now and then. The reviewer said that the DeLorme may be the easier alternative, but getting a budget-priced, dedicated GPS navigator will make you a whole lot happier.
