VOR

I made my first flight with my new avionics! As far as I can tell, the equipment works perfectly, although the pilot could stand some improvement.

One thing I could not do was get the unit into VOR mode. I could tune the frequency, and I could make the VOR part of the flight plan, but no matter how I tried, I could only get modes of GPS or OBS in the top right corner. I couldn't make it go into VOR mode in the plane, and I can't figure it out from the pilot's guide either.

I was able to put an ILS in the flight plan and I saw GPS->VLOC during vectors to final, and I got the ILS in VLOC mode through automatic switching.

How do I tune and fly to a plain old VOR?

I could have sworn that I tried that, but maybe I didn't.  Maybe I just pushed it a million times.

I would suspect you were pushing that knob as that is what would continually switch from GPS to OBS.  As was suggested, turning that knob should put you in VOR mode.
