Autopilot will not follow GPS

[petejohno]

For what it’s worth, I have discovered the AP in the Arrow will not follow NAV until you activate the heading switch. Not the rotary, but the large rocker. You also must have the rotary set to NAV, not HDG. 

That is the case for me and I was going to report it as a possible bug bt hopefully this will suffice.

Thanks Arty57.

That's the way the auttopilot has always worked in the Arrow. So it's not a bug.

I have tried with both the turbo and normal arrow and same thing. Seems to be a problem with the TDS GTN, although I never had a problem before the updates. I'll keep tinkering, but I'm running our of ideas....
