Thanks, good advise.
As a matter of convince, my GPS and CB are powered off a cigarette lighter. Yea, I know that is not the best, but redoing the GPS would be a major pain. My problem then was that I had a background buzz in my CB and every time I started the engine, my GPS would have to reset taking time to find satellites, and breaking the "tracking record".
I ran no. 10 wire direct from my battery (both +&-) to my lighter power, so I already have that no 10 ground wire under the dash. No buzz, no re-starts on the GPS. I already have a central fire wall ground.
