Can someone help me. I am a little afraid of patching my new gpsmap 62sc because of the warranty.I have FW 2.40.I am not sure having very well understood how to do:I put the patched gupdate.gcd in garmin folder, and after I switch on the gps without usb cable. And if I want to come back to the non patched firmware, I replace patched gupdate.gcd with the non patched gupdate.gcd. Is it right or wrong? Is there anything else to do?
Thanks for your help
