Hi Allan, its nice to see this. I am rebuilding a 180 from the ground up and will be putting an Aspen, KNS430, and an S Tec 50 autopilot in the new panel. Have you done any approaches with the Aspen coupled to the A/P yet? I may contact you again when I get closer to installation, this rebuild is a two year project for me. One question, where would you get the UMA lighting from?
