i couldn't find the gps comparison thread. i am going to buy a GPS soon and only need to get one so i can get used to it before i go overseas at the end of the year so looking to buy in the next month or so. it doesn't need to be the latest and greatest but needs to have a big screen, route planning, connect to bike power etc. cheapish. is the Garmin 660 or montana or ???? still good enough and is basecamp (or google earth) the best to plan the route on. is the tom tom too simple?? anybody??
