Your key word is affordable. I know the Garmin 550-660-665 are programmable. The 550 isn't made anymore but there are still some new in the wharehouses.
I have both TomToms and Magellan GPS's and they're all good, but none of them are programmable...so I'm stuck with them telling me how to go instead of being able to program my route ahead of time and telling them how I want to go. Anyone know of a good, affordable GPS that is programmable? Thanks in advance!
