Have you tried seeing if the unit's lighting will activate when you turn on the navigation lights?
My new Yamaha 90 is lighted whenever the key is turned on, and was wired by the installation mechanic who also had to remove several older independent gauges that were incorporated within the new integrated unit.
Unfortunately, the boat is at the marina, so I can't immediately go out and see exactly how it's hooked up, but will do so the next time I'm at the lake, probably sometime over the weekend. Joe.
