Hi.
I have dual 4500 EFIS, 430W, TT A/P. During a flight this past weekend, I was experimenting with the internal navigation features. I created a route on the 430W and aligned the EFIS to track. I then went to the EFIS A/P page and adjusted the flight plan. On initialization, the system asked if I wanted to switch to internal navigation. I said yes. Plane tracked fine to new route.
I then was ready to go home and entered direct to my home airport on the 430W. I switched source on the EFIS route page to external 430W. The plane tracked to my home field. BUT, the moving map display (secondary EFIS) would not show the route.
I cleared all routed and tried again, direct on 430W to home field. A/P tracked fine. But no route showing on map display.
Ideas?
