Just bought a used 60csx online. Lil' booger came with a SD card with CN 09 on it. I already have one 60csx (and no CN) so I popped the card in and Presto! that card works great on both units.
Decided that I wanted CN on both GPS units, so I decided to try something. I copied the card and sent the contents to a fresh SD. Guess what?....now I have CN on both handhelds. Outstanding!
I love the topos you guys build here (that's what I've always used on my old 60csx). Decided it'd be nice to copy the CN mapset to Mapsource so I could make one giant smorgasborg gmapsupp file to burn to my SD card. That'd be groovy...just turn one CN or Gpsfiledepot topos when needed. Mapsource would not allow me to copy the CN maps on the SD card. Said something about unlock code.
I know from using your topo maps in the past that the map files are sent to one gmapsupp file. You can build a combo of whatever maps are in Mapsource, but when you send a new mapset, the previous one is erased. Is there a way to have CN and your topos on one card?
