Thanks guys - I was getting lost on the internet yesterday.
So, plug the Suzuki interface cable into the diagnositc port in the engine, thereby allowing the existing guages to continue to work, then plug both (one cable per engine) into the Garmin NEMA 2000 starter kit (just one of those), then plug that into the Garmin 750s plotter.
Just what does the Suzuki cable do then ? Why dosent the engine info just flow out of the engine into the plotter, why do you need an interface ?
From what your saying Erin, I need to program the interface with something ? Would a Suzuki dealer do this ? Is this info to tell the plotter stuff like engine size and fuel tank size ?
