Whoa that was fast, thanks! I will try the "cat" command tomorrow when back on the boat. Didn't know that was possible, and indeed will allow me to diagnose where the issue is.
As for wiring and polarity, i can check all the possible permutations, but i just found this table that might be useful (Never occured to me that + => B- and - => A+
):

Regarding the baud rate, i'm not sure where to find it, as i can't find anything on Garmin's or VHF instruction manuals, but i will try with the most usual ones.

Nice tip, didn't think of it, will definitely try again tomorrow.
Thanks again, @abarrow
