I just can't seem to make it work, I tried to unzip the file right to the SD cardI (with a garmin folder on it) and then unlocked the file. The 3 downloads combined ito 1 file and then I ran Fast IMG unlocker my GPS Map 4212 says unsupported format. It's an IMG file just like the maps pre-installed in the unit. The garmin website says US Inland Lakes is compatable.what am I doing wrong?
