The old King KLN94 GPS and KT76C transponder was replaced by the Garmin GNX375 a combined WAAS GPS navigator and ADS-B in/out transponder. The attitude indicator, directional gyro and VAC system (dual VAC pumps) was removed and replaced by a Aspen Avionics E5 EFIS with “advanced features unlock” that includes OAT and winds. The GNX375 has an internal bluetooth transceiver and built in backup AHRS (requires an Ipad and the Garmin pilot software) so we also installed a RAM mount for portable electronic devices and a Garmin GSB15 dual port USB charger.
