Bonanza TC. I have the GTN750 and 650 optioned. Can't figure out how to get the OBS/VOR2 needle to kick. It is always static with red flags on it. I've tried tuning it on the the KNS81 but I must be missing something.
The KNS81 is displayed on the CDI only when "RNAV" is selected via the source select switch beneath the CDI. VOR2 is controlled via the GNS 650 in your configuration.
