this gp be ok . when I start look at different model to replace my old Magellan -lrb- obsolete because they stop release map update after I have it one year -rrb- I see this one and just have to have it because of the big screen . now that I have it I kind of wish I get a smaller one and save some money . the big screen be nice , but I can see my old one with a 3.5 inch screen just fine , so I do not really need such a large screen . my main gripe with this unit be the pathetic little mount it come with . the mount be so tiny that it be useless , and , of course , they will sell you the proper mount for a extra fifty buck . so that seem a little dishonest to I . so if you be consider this unit , figure on spend the fifty dollar more , and just order the right mount at the same time and save yourself a headache .
