Ok, I double checked, By default 13/14 is assigned (and should be set to in your case) Plus and Minus under the major category “Miscellaneous”. Make sure OBS on the left is set to VOR OBS under Radio > VOR. By default the IAS position is set to BOTH “set autopilot airspeed hold” under “Autopilot” which is INCORRECT (remove that) and then IAS, HDG, VS, ALT should all be set to Select Airspeed Bug, Heading Bug, VSI Bug, Altitude Bug under “Instruments and systems > Flight Instruments”. This works for sure on all the WT Gxxx series including the NXi and I believe I’ve tested it with defaults as well, but it should definitely work on defaults.
