Please accept my apologies if this matter is already covered but I cannot find it. I have downloaded the mapsource version of the latest map but where can I download the image file that I can install or load to my Garmin 765t? With mapsource I can only load selected maps to my unit but I would like to load the latest map to my 765t. If there is already a post detailing how to do that, can you please direct me to where? I can't find it. Thank you.
