22 Makai / NMEA 2000 auto volume adjustment

[shawnrw]

Does anybody have any knowledge/info regarding the NMEA 2000 architecture on a 2022 Moomba Makai?

I'm installing a RA770 head unit and wondering if it is possible to provide speed data via the nmea network to allow auto volume adjustment.

The 7-inch screen manual says it supports this network currently.

Not sure about the 7" screen interface.

I know when I upgraded my stereo I had to add a power pigtail to the nmea2000 network. The RA70 provides voltage to the network but the other stereos do not provide power only signals. I was making my transom remote work. You might also need an additional Tee and terminator.

I have been looking for NMEA 2000 answers as well. I believe the factory ITC RGB controller may interface with the screen via NMEA2000 which would make it easily addable to control the RGB via oem screen but I can't find out how it communicates with the RGB controller.
