Stephen,
As I mentioned before, there is only ONE GPS antenna that will work in conjunction with your Sea Ray Navigator, which is the one we provided Sea Ray when they bulit your boat.
No other GPS will be able to be connected and/or work.
Are you having a problem with the Maptech provided GPS?
If you are, we will be more than happy to diagnose the problem and possibly replace if need be.
Maptech Sea Ray Navigator tech support can be reached at 978.792.1035 Mon - Sun.
