Thread: Strange thing when Unlocking 24k TOPO

I have a Montana 650t and have D/L the 24kTOPO Mid-Atlantic that SkyGear had placed on TPB.

I ran the IMG using FIU and assumed it should/would remove all locking on the IMG.

Then I copied the unlocked IMG to my Montana, but kept getting a message "Can't Unlock Maps" on the Montana.

I tried it a couple of times thinking I may have made an error, but nope, I did it correctly with the same error message.

Any Ideas? Do I still need to generate some sort of UNL file or somehting else ?

Thanks.
