Spent today reinstalling the avionics, updating software, and validating it is working. Ran into a problem with the device that splits the audio and rectifies it to a standard audio signal for the in flight recorder. Unfortunatly it seems like it may have back fed some power and potentially fried the data recorder and the audio output for the SL-30. I'll have it checked out and see if that or the audio panel took a hit. Also backed the fusalage out so all of the GPS equip and the SiriusXM reciever could update themselves for the first time in years. They all updated and are good to go.
