Garmin Question

[OakLeaf]

Garmin fitness units do not come with MapSource. You need to purchase one of their other software packages like City Navigator to download directly via MapSource. (The exception will be the optional memory card that will come with the new Edge 605 and 705, whenever they're released, but I'm not holding my breath.) And you can't upload any maps to the fitness units, excepting again the future 605/705.

SportTracks is a shareware program (Windows only, but it works under Parallels) that will download data from Garmin fitness units and display your track superimposed on a Google map; you can then save that image. IIRC you have to be a MotionBased Premium member to be able to save the Google maps displayed there.

All of this is probably no less hassle than creating the route manually in DeLorme Street Atlas (likewise Windows only but Parallels friendly). DH has been using GPS navigation for a decade now and is convinced that that's the best software package out there. Street Atlas definitely addresses the issue you found of roads not being in the software's maps. They update their maps annually. And if you're riding through either a brand new development, or a bike path, you can use the software's Draw feature to create the new road yourself and allow future routes to follow it. Unfortunately, the interface is not very intuitive, and you can't display Street Atlas maps in Training Center.
