I'm basically looking for a nod of approval here. I've exhausted myself reading all the forums I could before posting. Here's what I need and have done..... Downloaded myself the lake of the woods/rainy lake G2 Visions map from TPB and put the zip file in a folder marked garmin on my sd card and renamed it GMAPSUPP.IMG. I then placed Fast IMG unlocker in same file and got it to do it's magic. I have also used the jetmouse key gen with the 421s unit id and the mapid of 487,1,1,52 and generated a code. I placed the generated code on the first line of notepad and saved file as all types GMAPSUPP.UNL. I then also placed the unl file with the img file in a folder marked Garmin on my sd. Is this all I have to do to use this map on my GPS 421s fish finder? Will having the .unl file in the folder make it not work since I used the unlocker? Sure hope I got it right, It's a long drive to my boat just to see if I got it right or not. Made for a disappointing weekend last time, lol.

Cheers to everyone for what I've read so far!
Crossing my fingers I don't loose the bottom end of my boat!
