You could put ALL of SMTS (or GWT, or Mex2Can, or even ALL of your track files together) on a single map overlay. Then load it onto the uSD card in your GPS along with R&R. Then copy that IMG file to other uSD cards or post that map file on the internet for anyone to copy themselves. Call it "Coundown's map to the World"!.
On rides, customer needs to turn on and off tracks as they ride.
On my big files like Death Valley on GPSXchange.com people need to cut and paste tracks t plan their trip then load into GPS (they could use it).
I think the big application is for OHV riding areas like Jawbone or Rand Mts with designated routes and many closed existilng routes. Some forest in the midwest has it available after travel management. Riders could just download the IMG file with no maps and have a good ride.
For my use, I think just moving up to 78 with 200 tracks of 2,000 points does what I want.
Good point on (useless to me) GPSs that don't take tracks like Zumo.
