I purchase this in Sept 2011 . work ok to begin with . then it start freezing up , but I could cut it off and it would get ok . on 2\/23\/2012 , it freeze up again while down town Detroit and I try to get out of that city . this be just a piece of junk . it be still freeze up and I will probably purchase some other type of GPS . I would not reccomend anyone waste they money on a GARMIN .
