I just picked up a 2 GB card for my 60 CSx and I've got a few questions. My plan is to load as much of the U.S. as possible from Mapsource onto the 2 GB card and leave it in the GPSr. I'll keep the 64 MB card that came with the GPSr as a backup. For example, I might put TOPO for a specific area on the 64 MB card. Once I'm out in the field, can I swap cards on the run without loosing my other stored info such as waypoints, routes, tracks, information stored in the calendar, etc.? Also, when I store the 64 MB card, do I need to take any precautions to keep it from degrading? I was planning on wrapping it in tissue to keep it safe from static, put the tissue in a small ziplock to protect it from humidity, and then keep it at room temperature. Is this good, bad, overkill, insufficient....? What's the best way to store a memory card? Hope you're all having a great holiday weekend and finding lots of caches. I'm power washing and re-sealing my siding and decks. Anybody want to trade places? Thanks in advance for the help. I'll check back later. My deck is calling me.
