Sorry all but I'm a bit thick today. I tried copying/overwriting the gupdate.gcd file in the garmin folder on my device (GPSMap66sr). After connecting I couldn't see an existing gcd file even after reinstalling the software using Garmin's Webupdater. Just to try i copied GUPDATE_Patched_JNX.GCD and renamed it to gupdate.gcd but ths doesn't work either. Am I missing something here?

After flashing it disappears, see the firmware version in the navigator.
