For those that get a Garmin G5 left of the G3X they get the GTR-200 over the GMC 305 on right. I'm not sure why 305 vs. 307, I much prefer to have the knobs at times it's easier in winds/turbulence. If the autopilot was mounted over top of the GTR-200, would that solve the problem and allow a 307 to be used on the right?
