First Thanks Cannonshot for all your work. I thoroughly enjoyed your ride report. I need a little help loading this file. I have a Mac.
So do I need to buy Mapsource Topo US and install it into my Mac?
Then do I down load Cannonshots gps file ?
Then how do I transfer the files to my Garmin GPS 60 csx ?
Is there another program I need to buy ?
Do I put an empty SD card into my GPS before transferring the files from my Mac ?
