Hello,
I am successfully using the GTN application with the C172 (round gauges). I am able to use the GTN to drive the CDI in NAV mode following a VOR. When switching the CDI source to GPS (using the C172 panel or the GTN CDI button), the CDI just stays centered and does not show any course deviation. The nav flag is not up.
How can I get the GTN GPS to drive the CDI show I can fly a GPS approach?
