Magellan GPS 310 1.5-Inch Portable GPS Navigator Review

Average Reviews:

(More customer reviews)The Magellan 310 holds 100 waypoints in memory. Higher priced units hold 500, but since I am not a "world traveler" 100 is fine with me. The unit does not come with an NMEA cable to connect to a PC, but Magellan will send you one free if you pay the 5 dollar shipping charge. The owners manual explains all of the features of the unit in sufficient detail that even I can operate it.
The manual is overly pessimistic in regard to the time the unit takes to "fix" a location. The manual says 2 to 5 minutes for a location fix, but I get a "lock" in 30 to 50 seconds most of the time. Sitting on my sofa, in front of a window, the unit obtained a postion fix in 45 seconds with the venetian blinds only partially open. Venturing into a desert canyon the unit performed even faster. With most of the horizon blocked by the canyon walls the 310 locked in a postion fix in 30 seconds.
The 310 also performed well in a moving car, with the unit propped up on top of the dashboard. In the moving car the 310 maintained a lock on enough satellites to register speed of travel and a working "North" arrow.
It doesn't have the bells, whistles, moving maps, etc. of the higher priced units, but it does what I wanted it to do when I bought it.
