travel from norther Michigan to Indianapolis , in the middle of the night , this unit direct I off the highway way before I be to get off . travel about twenty minute I come to a town , the road be close and there be no way around the town area to proceed further . . we waste a hour at 1am , when we should have reach we destination and be in bed . . instead , we have to turn around , drive all the way back to the highway ... then trust this instrument to bring we in from another location . . I have not trust this unit since ... I have try to hook up to we computor and TomTom do not recognize my password , and no matter how hard I try , I can no longer up date my TOMTOM ... I be very dissappointed in this unit . . and try to find a phone number seem impossible . . also , it have time of not show street name when you need they . . they color line cover the street name ... it be difficult to find where to navigate so you can look at the route it be provide you . . I would rather spend more time do seventy on the highway , than a direct , unfamiliar two lane road in the dark , no service station ... I have hold this next my friend 's Garmin , no comparison . . Garmin hand down win . .
