ok ... SO AFTER READING MANY REVIEWS and be a little weary , I buy this UNIT ON SALE at TARGET for $ 179 . OUT of the BOX IT WAS great . the map update work fine , no problem with the activation code . change my route take the UNIT ABOUT 10 SECONDS to CORRECT the route . turn it on TOOK ABOUT 4 SECONDS to acquire the signal . everything work fine , from the ETA to your destination to the speed limit warning . it be a bright display and good for my old eye . I would RECOMMEND THIS if you want to spend that much money . I buy a two year WARRENTY for $ 17 . and FEEL COMFORTABLE ABOUT OWNING IT if ANYTHING GOES WRONG . no PROBLEMS SO far and be very happy with it .
