Ok - the system works BUT!
When I can get ON it won't shut off and when it's off it's nearly impossible to get it back on. Once the system is on it does function properly. I've resided myself to just leave it on and every time is run the boat I just bring the settings up to the MPH max of 35 when I want to run the boat faster than surf speed.
This is an 09 24SSV so the system is not a stand alone gauge but rather it's integrated into the helm........the control pad contacts work for all other functions so it seems like it might be the Supra brain box.
Anyone experience this in the past???
