Received my new Garmin 276C last week and had it hard-wired by my trusty tech yesterday. I've had a chance over the past week, or so, to play with it off-bike (battery power is really handy. Can't imagine not having it for rest stops, hotels etc.). I've also played with Mapsource as I bought City Navigator NA and a 256MB card. Though I've never had a GPS, I have used MS Streets & Trips on my PC for the past couple of years to plan routes etc that I then summarized on a piece on paper and stuck in the map pocket of my tank bag. Low tech, but did the trick. All this to say, I have not found Mapsouce to be nearly as intuitive as Streets & Trips when it comes to creating/modifying routes. Ditto for the GPS itself. Obviously I'll get better as I go, but has anyone else found this to be the case? Any tips? I've updated the unit's software and read the updated manuals online (hard copies were slightly out of date). When planning a longer trip, say 1200 kms/750 miles over two days, is it better to create and save as one route, or two? Does uploading the second route to my GPS erase anything from the first route, or is it only if you save maps too that erase any previous maps on the GPS. Any and all tips welcome.
