Autopilot inop since last update & GTN750

[VetteDrvr]

Hello, since the last update for P3D4.1 my A/P panel just flashes the barometric pressure.

I can't get it to turn on and when I click on any button like HDG or NAV nothing happens.

I cycled the circuit breaker and it still behaves the same way, all it does is just flash the baro pressure.

I'm using the Flight1 GNT750, have that set up via the MV configurator and I'm really at a loss. It's been a little while since I last flown it so I have no clue as to why this is happening.

Part 2. I can use my Chase Plane view to go to the 750 in the planes instrument panel, but it will not pop up when I click on the bezel like other planes I have, but when I press Shift 2 it pops up and I can use it, but only once. All over times when I invoke Shift 2 the screen is black. But while it's black if I click around on it I can see the one in the plane's panel do stuff, like if I get it right I can click on the black screen and bring up say map view on the instrument panel but not the 750 that's popped up via Shift 2.

This is the only plane in my hangar that the 750 works this way.

Thanks.

Hi,

Did you press on the BARO button to accept barometric value?
If so, was the AP working fine with V4.0 and went wrong with v4.1?

Yes, it was fine in 4.0.

I did press hard on it and can get it to work intermittently, but it's very sporadic and random to get it to work, and any button I click on gives me the high pitched chime, like I'm disconnecting it.

And, to make matters worse, the sound of the plane is horrible. It cuts in and out in both inside the cockpit and external views, it goes up in pitch and sounds like something is dreadfully wrong.

How did you upgrade to 4.1? Did you install client.msi alone, included content.msi? or a full install, all modules?

Tomas

Client only. I rebooted the PC a couple of times and now have the A/P working. Also the 750, but the sounds in external view, I have full throttle sound and idle at the same time, very odd.

[Taguilo]

I recommend you install content also, it's not too heavy and might help to solve problems

Thanks but I'll pass, I have no issues with any other planes, planes as complex as PMDG & A2A, add-ons like Chase Plane, AS4, REX, PTA, GTN, just the Beaver.

Thanks anyway for your help.
