First - any help much appreciated...
I have some Garmin marine maps that I need to load on a Garmin 741sx. I have a Mac, operating on OS X (Yosemite, 10.10.5). I don't want to run Windows on this Mac.
I tried the gimgunlock.exe thing, no dice.
Here's what I know:
The files are all named like this: gmapsupp.img
When put on a SD card, Garmin does not recognize these files
That's all I got. Where am I at in this process, what's the next step?
It worked some months ago when I tested it in my virtual Mac.
Mostly these tool are developed for Windows
