I've had this happen a few times no idea what's causing it.

 

I try to fly on autopilot NAV mode with RXP GNS530W - CDI on GPS.  But the aircraft won't follow the track, it just turns to the right.... and will keep banking.

 

Any clues?

You find out let us know. Iv flown 100's of flights with the RXP with no problems, but and on rare occasions, specially when switching  aircraft, ive noticed the same thing. Not following LNAV path. Seems like after the first waypoint it regains LNAV capture.. Restart flight and it flys to the first waypoint fine.

I was flying the RA Legacy.  Did an ILS 24 into KCRQ with VTF fromt the PE controller.  I overlaid the VTF on the Garmin but flew with VLOC.  I landed.  I then did a quick turn and deleted all the waypoints on the garmin, and entered a new flight plan.  When I got airborne the garmin had SUSP in the lower left (suspend) and I just pressed it to clear it (from the old FP).  I'm betting it has something to do with that.

Using Opus?

Affirmative... But not the camera stuff
