This is a picture of Larry Bahl’s panel in his 1968 Cessna 210H after removing his old radios and having a Garmin GTN-750, GMA-35c, GNC-255, and GTX-345R installed. He also had an S-Tec 30 autopilot with ST-901 GPSS installed. This installation was in May 2016. Larry is currently considering his next option!

This is our most recent installation. This aircraft belongs to Forrest Ward. In June, Forrest had his Garmin GNS-480, Avidyne MLX-770 Iridium Satellite Receiver, and his PS Engineering PMA7000 removed and replaced with a Garmin GTN-650 GPS/Nav/Com, GSR-56 Iridium Satellite Receiver, GMA-350Hc Audio Panel, and GTX-345R Transponder. Forrest has since added another GTN-650 GPS/Nav/Com.
