Philbert40, just about ALL the Garmin GPS's will allow you to download a route from your computer. If you are going to use this on the bike, I would recommend getting a Garmin ZUMO model...as the ZUMO's are waterproof. I have a century old Garmin Zumo 550, and it still keeps working. A used 550 goes for more bucks than a brand new 665 or 660, because of the supply/demand of the 550.

The Zumo 350 is a very good unit, and if you want a 5" screen, then the 665 or 660 are the units to get.
