RWAMF,
I've been using the H2Oc for a couple of years now with the MapCreate 6.3 TOPO software. The H2Oc does everything I need but the screen can be a little tough for my eyes to read. I see that you also have a H2Oc. Do you see any differences between the XOG and H2Oc other than screen size, touch screen, and mpeg player? Does it lock satellites as fast? Can track recording parameters be changed (like on the H2Oc)? I'm assuming that an SD card loaded with maps/routes/tracks for an H2Oc will plug and play with the XOG.
Thanks
