My Garmin 420W is not seeing baro altitude from the D 180. There is an HS34 installed. Am I missing a set-up step?

Baro altitude is needed by the GPS for climb-to-altitude legs (or any leg with an altitude terminator) before proceeding on the next procedural path/terminator segment.

On the 420, what do you have your arinc input set to? It should be "High and "EFIS / Airdata"
