Installed in a 25 ft center console
The controller is well made and the ports are well placed. The onboard GPS is very accurate even when installed in the helm of a center console with a t top. I added the button security snaps for the boat cover. Alerts are sent within seconds of the buttons unsnapped or boat being moved out of the geofence. Tracks are spot on. Best is when I connected the Yamaha connector to the nmea2000, I get fuel, engine hours, fuel burn, rpms etc. app works great!
