G1000 OBS function

[SkyBarca]

I am sure I am just missing something but I can not get the OBS function to work on the PFD.

In GPS mode, the button is usable, but I can not find any control that actually changes the setting.  When in NAV1 or NAV2, the button is not even there.

This makes anything but a preset GPS course unusable for me.

Can someone please educate me or point me to the correct manual?  The default G1000 manual is pretty clear, but the Baro knob on the TBM900 PFD does not have a cursor ability like the default G1000.

I haven't used it for some time, but I think it supposed to work only in GPS mode. It makes G1000 stop following flight plan and treat current waypoint (doesn't need to be vor or ndb, it can be just any fix) as navaid. You can use CRS knob on MCP (or whatever the autopilot panel is called in this plane) to set it like standard VOR HSI. You can use it for example to hold over non-navaid fix. I think that original G1000 documents would explain it well.

Course knob on the AP panel adjusts it in all modes. Thank you!!  That was driving me nuts.
