You can also just put in a start and a finish and let basecamp route it, then use the insert tool to shift the route over to roads you like. Escape gets out and ctl+z is undo. Takes some time to get the knack of it, but if you have your basecamp preferences set up to how you like them so that the way it calculates is pretty close to what you want, then run along it with the insert tool and stitch it down or move it to the roads you like. Until you get a feel for it, make a contrasting color route so you can spot deviations easily. If you can see both on your gps unit screen, so much the better, so you can find out just how much adding of via points it takes. The video tutorials are decent, too.
