Unable to transmit or receive either com through audio panel. Checked all wiring...OK. Flew to Hampton Roads, VA to swap audio panel with Ed Smith. Ed's panel was not the same as mine so no help. Visited Jim at Bay Avionics at Hampton Roads. Jim said that the audio panel had to be "programed" by a dealer via computer. He programmed it for me for free!
Re-installed audio panel. Tested perfectly. Transmits and receives normally on both radios.
Spent a lot of time setting up the GRT screens. Everything working well except unable to get SL-30 info on the bottom screen. Will call GRT after Thanksgiving.
