i have the garmin gps 340 street pilot. with 2 children in college and both of them driving there on their own i could not rest any easier knowing they have this gps.i used to get calls from them for directions when they got lost but they both have this gps which was very reasonably priced and very easy to use and now they do great. i would very much recommend this unit. it has never failed and we have never had a problem.
