I give the 1450lmt to my wife for Xmas . I have register it and update the map 3 time . however , the Garmin briefly flash a message `` no technical detail ... '' and then go to another screen . so , I have not read the entire message yet . but , update the map take 39 minute on my high speed line . so , this have already take nearly 4 hour follow a 4 hour charge period , and I have accomplish nothing . I send a message to Garmin and the automatic response state they try to respond to all email within 3 day . I read several negative review prior to purchase the 1450 , and now I wish I have not bother . the 1450 simply be not ready for the market .
