AURA, Motorola's two freshest navigators don't look half bad. Up first is the dead-simple MOTONAV TN20, which provides spoken street names and turn-by-turn directions, NAVTEQ 2D / 3D maps of the continental US and a 3.5-inch touch panel. The slightly more sophisticated MOTONAV TN30 picks up where the TN20 left off and adds in maps of Puerto Rico and Canada, four million searchable points of interest, a 4.3-inch touchscreen and Bluetooth handsfree support. Both systems include a SD slot for updating maps, a mini USB port for charging, speed limit display with warnings and the obligatory on-screen speed, distance, arrival time, elevation, and distance traveled tidbits. If you're into either, you'll have to scoot over to the RadioShack most convenient to you and plop down $199.99 / $299.99, respectively.
