Hi. I’m looking way to connecte navomatic 300A (CA395A) to Garmin G5 via Gad29b.
I can’t find any wiring for this ap.
This is a rare one. Google finds the user manual only, it seems. No installation manual.
Some US sites say it is driven from a fake heading bug the whole time.
Check your email also…
What’s a ‘fake heading bug’?
No idea, but perhaps you have the answer for the OP?
If the interface isn’t shown in the G5 STC installation manual then it’s not approved so can’t be used.
ARC/Cessna avionics equipment tends to have non-standard interfaces. For example, the RMI used in Cessna 1000 installations used a VOR composite signal which is 180 degrees out-of-phase with that used by King, Garmin, Narco and Collins!
The aircraft may be homebuilt so the legal issues won’t exist.
It won’t have a Cessna autopilot in a home-built.
