Looking for western gps maps for my Garmin 60CSx. Specifically, looking for western National Parks. Every place I've searched for this product online says "discontinued" or "not available". Anybody have this software? Any idea who might carry it? Or maybe it was discontinued for a good reason, as lots of discontinued products are. Anyway, I'm looking for 24k scale maps of yellowtone, tetons, grand canyon, yosemite, etc. Any ideas appreciated.
