Trying to use NextSwath on a tractor for the first time and not having luck. Have a NAV2 and a 2050 display. Version 13.75.018.4 on the NAV2 and 11.28.001.02.3 on the display. On the fmx+ run screen it tells me I need OnSwath enabled. Under settings for NextSwath it tells me to upgrade AutoPilot to enable OnSwath. What do I need to do to make this work?
