OK I have installed a MG XI5 and connected it to my HDS9 live. Obviously with the gateway kit and the NMEA 2000.
I have seen on line that several say the NMEA should be on a switch to power it on after you power on the trolling motor and depth finder. I looked all through the NMEA instructions and can't find anything referring to that. What do you you guys do and why? Seems like it would be a pain to have the NMEA off until after you deploy the trolling motor.
