I was at my local airfield and decided I'd better do a VOR check (checkpoint on the field) before takeoff and was unable to select VLOC with the OBS button on the IFD540. I had the appropriate VOR tuned into the VHF NAV frequency, and the VOR info was in the tab, complete with VOR radial and distance. I already had an active direct - to GPS course set in the flight plan and no matter how many times I pushed the OBS button, I couldn't get it to switch to VLOC mode to accurately check the VOR with my Aspen PFD.

Is this an issue with the logic of the 540 or did I do something wrong?

If you push the CDI button it will take you to OBS mode. You need to rotate the knob to select VLOC mode.

Operator error. Thanks Gring!
