Anyone know of a good fix for this. My Navionics chip in my Humminbird 385i's SD slot frequently refuses to load charts unless I push the card in and out a few times or sometimes wiggle it.
Any of the electrical component cleaner sprays I have looked at have warnings about electronics and circuit board damage etc.
