Hi all. New member and first post.
Just moved from Florida to Georgia and bought a new Navionics Gold chip for my 987c SI. Unit was working fine, but when I installed the new chip, MSD/1XG, my unit would turn on for a minute or two then power cycle. Just did a firmware upgrade, v4.770, and the unit is still power cycling with the new chip. I can get good cartography images for less than a minute, then it cycles.
Works fine with the old chip with the new upgrade, except of course no local data. Any suggestions to fix the issue?
