I receive the 3790T Garmin GPS for my birthday at the end of July . it be beautiful , thin and sleek . the feature that it tout be amazing . the picture clarity be impressive . we use the GPS for a trip to Canada and it perform well -lrb- minus a few exception of it alert we to traffic congestion , when there be none . -rrb- shortly after that it begin to have difficulty turn on . on a trip to a nearby city , I want to find alternate route to my destination , after it finally turn on , it would not recalculate the route in time for I to make the necessary directional change . the popup ad be terrible , I do not really care for $ 5.99 all you can eat Sushi . once those stupid ad pop up , they would not clear from the screen so I could continue navigate -lrb- the screen would freeze -rrb- . after that trip , when I return home I shut off the gp and it never turn on again . I try reset it , charge it etc. , it still would not turn on . what a disappointment . I have not even have the GPS for two week before it break . I too have issue with it get hot , but live someplace that we use the ac year round , so I would turn the ac unit on to the defrost mode and it would cool the GPS unit down . I be disappointed that my new GPS unit fail after only two week and I despise the stupid popup ad . I like the feature that this gp be suppose to offer , but I doubt I will go with another Garmin due to the poor quality .
