I be very happy with the Magellan map 330x gp . I have purchase it because , for the price , it be better than any of the other brand . it have a good battery life -lrb- 9-10 hour from 2 aa depend on how often you use the light feature -rrb- , and come with map software which be a must for this type of GPS . the feature it have meet or surpass other product in its class . the only problem I have with it , be that in order to see any local street you must be zoom in pretty close , but you can not expect much more since the screen be only about 3 `` x2 '' . I feel that its very accurate ... with the map software I can see all of the rural street around my home . sometimes it take a while for the unit to orient its self , but once it have go through its cycle it stay lock on , even in my basement . I do my homework on this one , and I would recommend it over the other brand , unless they can come up with a better package ... though the other might have product in the same category , they do not package they gp with the software and the datum cable so they can ding you with the cost of buy it later . ... it would be worth you while to do some research before you buy though , so take the time to look around on the above web page , and visit epinions.com to help you make a sound purchase .
