So I started studying the G1000 (Nav III) for the Cessna and spent 20 minutes in the simulator trying to figure out how to tune an NDB when I looked it up in the manual:
The G1000 does not support tuning of the ADF in Nav III aircraft. ADF tuning is accomplished through the Bendix/King KR 87 ADF Radio. ADF volume must also be adjusted through the KR 87.
A top of the line system doesn’t even have an ADF/NDB radio built in? WTF.
So you can get ADF info on the PFD, but you have to use and tune an external radio.
Boourns to that.
