I know you can split screen Mega 360 with 2D sonar or down imaging with a 10" Helix unit linked to a properly equipped Ultrex TM.
Can Mega 360 be used at the same time with the Chart functions "Follow contour " or "Navigate (saved) route " ?
Seems like I read /heard somewhere that there was not enough memory to run these features at the same time but I can't find it anywhere now ?
