I have the 62 (with three letters after) Garmin. It comes with the US map on it and I put in the Canadian Map (or at least the part I use). I was under the impression that I could only put a limited number of tracks on the unit, but upon reading I can put as many as the SD card can hold over and above the limited number. How do I know what is on the card and what is in the unit memory? And does anyone use these cards to manage different areas like BW and WCPP?

I no longer have a Garmin 62ST, but still have the computer programs and maps.
If you transfer a custom map from BaseCamp to a chip for your unit, it does not impact the number of waypoints or tracks because they are a feature of the map installed. I had 10 maps on the 16 GB chip in mine. And could layer them in the display.
I think all the waypoints and tracks are stored on the unit as .gpx files, can not remember the exact directory location.
My Delorme units have similar restrictions so I remove/transfer all waypoints and tracks soon as I get home from a trip. Once on the computer, saved for future use. Keeping the internal and chip memory cleared of them. I can install a full BWCA-Quetico mapset with all portages, landings, tracks, and campsites as a map and not affect the limits on my unit.

stc?

I have dabbled with saving waypoints, tracks, and customer maps to a chip, but the benefit of having the Garmin UMFG chip in the unit 24/7 usually overrides any desire to pursue it much. I often am more interested in the lake depth lines that this chip offers rather than plugging in a different one with oodles of custom maps or tracks available.

Similar to what butthead is saying, I use BaseCamp to store my tracks and waypoints so that I can delete them from the unit and save space for new ones. I'll move subsets of this data back to the unit for particular trips, but some wacky things happen when I drag them directly out of BaseCamp back to the 62st. Because of that, I try to remember to copy these files in the Finder on my iMac instead.

The path for the files on my 62s is Garmin/GPX/... for tracks and waypoints in gps format and Garmin/CustomMaps/... for maps I have georeferenced in kmz format.

schweady, did you ever try installing or transferring the UMFG map to your BaseCamp program?
I ask because I did that with RedPine PaddleNav, worked well and can be sectioned and installed onto micro chips after. In that way I could add multiple maps to one large chip.

I have looked at every possible way, but think that since it is a Garmin product on a chip that specifically stated that it could not be copied or transferred, it is marked in some way to keep it protected. The files in the Garmin folder on the chip can be copied to my Desktop, but they all lead to dead ends:
GMAPSUPP.GMA (shows as a Garmin MapManager file, but says 'Install these map(s)?' and then no map names in the listing)
GMAPSUPP.IMG (shows as a disk image file, but says 'no mountable file systems')
GMAPSUPP.UNL (shows as an EXEC file so unreadable on my iMac)

Thank for the info. I have no experience with "locked Garmin maps", so did not know if that is possible.
