No GPS

[Stephen Denmark]

Hi

On way home, got a NO GPS warning on both EFIS 4500 screens. GPS function and signal were fine on the 430W. GPS signal going to TT autopilot was fine. Landed, shutdown, and rebooted everything and once 430W had a good signal, the AFS boxes were fine and all warnings were gone. Any ideas??

Did you switch the EFIS screens to another GPS source?

D0 you have a loose wire?

I only have the one GPS source; 430W. No, I did not switch.

I landed, shutdown and refueled. Restarted and all has been fine for 3 additional flights.
