Ok, I'm not the brightest bulb in the pack. But, I can't seem to figure out how to get the Airbus autopilot to track a vor. I change the frequency on the nav 1 radio. But I don't see a switch to tell the autopilot to move to nav tracking. The nav/gps light on the left has the nav light on. But the plane just won't change heading.What's the secret?Thanks in advance to all who reply.Regards.Bill

Try the LOC button on the Autopilot panelDavid
