I get one of these piece of junk for my birthday a year ago - I think it have work a total of once . first , the mount arm do not keep the product at a angle where it can be view . I contact TomTom and they tell I that my mount arm be not part of a recall of mount arm - so I have to buy a new one . I do - twice - neither work . I call TomTom again and they tell I that the mount arm frequently malfunction when the temperature be over 80 degree - I live in Texas - the temperature be over 80 degree 6 month of the year . next , I have to constantly restart the TomTom - it seem to not like to work for more than a couple of hour at a time . then , yesterday , I try to restart it and nothing happen so I box the whole thing up -lrb- 3 docking arm and all -rrb- and mail it back to TomTom . save you money - get a Garmin !
