GPS wire corrosion

[bijou22]

Hi,it says in the manual for my Lowrance GPS that it should be wired via a switch to prevent corrosion of the cables when boat is on a mooring. If I am removing the GPS after every boat trip,I do not see the point. Does anyone agree or have any opinions on this?

Without a switch there will still be 12V on the connector whether the GPS is connected to it or not, and the connector will be exposed to the environment.<br /><br />Garmin knows what they are doing. Use a switch.

thanks for that, guess I'll leave the switch where it is.
