Those ports on the back of the Map60CX are a weak spot, for sure.  Some 
folks have anointed them with dielectric grease (does not conduct), but 
then you have to worry about grit in the grease.  My solution is to rinse 
those areas with a little fresh water every evening after us, usually in 
the form of a wet tissue paper after wicking away any drops of salt water 
with a dry tissue.  Been doing this for three seasons with my 60C; the 
contacts work fine, and show no signs of corrosion.  It is the USB port 
connector that I am most concerned about, however, and I can't see inside 
on that one.

I think you're right -- the minicell pad does seem to reduce water 
intrusion, but there is still some water inside those rubber fittings.  Not 
a good job by Garmin, IMHO.
