682 shows that you have already patched your device

Just use your HWID 2588 in search this topic you would have found the solution already.

Hello,
I updated the firmware, but my GPSMAP66 still doesn't accept unlocked maps. I installed City Navigator® Europe NTU 2027.10 maps (new-maps/garmin-city-navigator-europe-unicode-2027-t24769.html), but at startup, it displays the message "Unable to authenticate maps. Contact your map vendor for assistance." Could you tell me what the error might be?

Thank you.

Thank you.

I've redone the patch above ,your Firmware should show 10.72."Unable to authenticate maps "is normally not to do with Patching
Try this small map to test.

GUPDATE.GCD lace the file in the GARMIN folder on the device's internal memory and then turn on the device and you will see on the screen that it is updating and when it is finished, it is ready.

16GB seems high for a Drive 50.Which maps are already on the device and which maps do you want to add ?
