This is my buddies boat I was just working on. Verified we have 12v at the plug near the head of the ultrex. Everything appears to be Hooked up. The mega 360 was used by another guy this year and when he swapped it to this boat it won’t work. We aren’t sure if it worked before or not as the previous guy that had it wasnt using it. I have never seen it not work before. It seems like once a 360 is attached to a graph it should automatically pop up the 360. On both his Solix units the 360 screen isn’t even on the pages. On my personal setup I’ve never seen the 360 not showing up. I’ve seen it not connected and grayed out so I couldn’t connect but I’ve never seen it not even show up on the screen.
