Electrical Question On GPS?

Does someone make a capacitor for electrical items on a boat? I have a Garmin 4008 and it is connected directly to the battery. Whenever I start either engine the voltage drop turns the GPS off. Its not a ground issue its connected directly to the battery and the terminals are clean, the batteries are only a year old and they are Kinetic 800 amp batteries. How do OEM installs of garmin GPS units handle this voltage drop...

Sounds like your two engines battery systems are tied
together so what I've done may not be an option. My 35
Nordic came with four batteries, two per engine. The two engines are not tied together. What I did is power my GPS from a feed that comes from two rectifier diodes from each feed.
