I purchase this product because my original Garmin I purchase over 7 year ago , I be not able to download current map , for whatever reason . I travel a lot and be look forward to use this Garmin everywhere I travel . it have a very short battery time and I constantly have to re-charge it and it usually go dead when I need it the most . it shut off in the middle of give I direction and when I power it back on , the Garmin screen be display something totally irrelevant and start give I wrong direction . I regret purchase it !
