Awesome! Just Awesome! That did the trick Whiter. Man, I had tried everything, or at least I thought I did. Interpreted webpages in 3 different languages, read page after page in forums, etc. Even read about the RGN tool at one point, but was in reference to accomplishing a different objective and didn't trust myself not to screw it and brick my Rino.
I really do appreciate all that's been done by the people here and elsewhere in helping others fully utilize what I feel is a crippled (purposefully) product by Garmin, at least from a software/firmware standpoint. Now I can custom map to my heart's content.
Again, thank you so much.
