The avionics upgrade is scheduled for November. It will include Dual G5s, a GMA 345 audio panel/intercom (removal of the old panel/intercome), 730 engine monitor, Flightstream 510 data card, and yoke covers with push-to-talk buttons.
This will elimnate the daisy cable headset setup we have today. The existing headset jacks will be used. It will give us accurate fuel flow/fuel remaining, and a replacement for the legacy engine steam gauges (including the inoperative CHT gauge).
