I buy a garmin gp 60csx for several hundred dollar for use in all situation , trail , water , road , and pay $ 100 in US road map softward so I could also use it in my car to find address . the software be very user-unfriendly . I do a search for a address in Florida and it can not find a street that be be there for 30 year . it do not even have Miami on its list of city . I be sure there be a way to figure it all out if I spend hour study it , but its Garmins non-user friendly system and you should not have to do that . it be crap . you would be better off buy cheap $ 100 car gp with free road map . but do not buy Garmin , they do not know what user friendly be . and get hold of tech support to help . you can , but the wait will be long , if not impossible
