To take a small step sideways, Mapsource software is one of the main reasons I started checking out Garmins. I wanted to get to my destination
my way.
The apparent ability to plan a route, save it as a file, and then share that file with others who would then be able to upload it to their own compatible GPS is intriguing. Couldn't successful and interesting blue road routes or touring routes could be shared over the net? I can see sub-forums of "Here is a good, scenic way to get between X and X," for example, where the route files can be downloaded.
Maybe I don't have the knack for using Google maps. For example, I planned last year's long trip on Google Maps and that little blue routing line, in spite of my best efforts, would often get itself tied up in a knots as I tried to plan routes. Often, I had to give up at start fresh. I lost a lot of time over this.
The other problem I have with Google Msap is that while you can import a route to your GPS from Google, I've not been able to do this unless the final destination was a business. The "send to GPS" link doesn't show for residential addresses. Also, once sent, the GPS would still use its own routing to the destination, not mine. All
of this can be accomplished directly with any GPS so why use Google at all? (I don't want this to be a statement of fact, though. Am I missing something?)
My (limited) experience with MapSource to date didn't have either problem. It was a lot easier to drag the route line around.
Still, if you don't add enough
viapoints between your
waypoints when going through an area with a lot of roads, the GPS may still route you it's own way between the waypoints rather that the exact way you want. Liberal application of viapoints in areas congested with roads solves the problem, though.
Don't know what I'm talking about? Neither did I at first. A nice person made a nice beginner tutorial here that helped me a lot:
