I receive the Garmin eTrex Legend as a Christmas gift . I have enjoy use it both in my car and while walk through town . it take a minute or so to connect with the satellite and then give you you latitude and longitude . while drive I let it hang from my neck so that when it be safe I can check it . if it be mount on the dashboard I would not be able to read it . the mileage travel be easily read and compare closely to what you get on the car 's odometer . I have find it fun to use thus far . I need to use the instruction book to learn some additional feature .
