I just got a Garmin 178C and Fishing Hot spot disk (with unlock codes) and am trying to transfer the maps on CD (now my computer) to a data card for the Finder. The problem is... when I transfer maps to my data card, it comes up on the depth finder that the maps are locked... They are unlocked on my computer, just when they get to the data card they are locked.

Is there something im doing wrong? or something special I have to do to unlock the maps on the Data card?

Thanks in Advance Guys
Larry
