Carenado Seneca NAV not working after Avionics Update

I removed the working title 530 etc yesterday and did a flight in the Seneca. The new 530 seemed to be there, but when I selected NAV or Approach mode in autopilot it did nothing. Anyone else have any issues with this for 3rd party aircraft after the AAU?

See bishop398 post.

Yeah exactly. Because they are used in more than the stock planes. Everything else seemed to work fun in the garmin unit but it was like the plane didn’t talk to it
