I ordered my avionics stack today. I’m going with a PS Engineering PMA8000BT audio panel and Garmin GTN 635. I went back and forth about both units a bit. I was originally going to install the PMA5000EX audio panel, but ended up deciding the Bluetooth functionality would be worth it for making phone calls and listening to music. I was also originally planning on installing the GTN 650, but ultimately didn’t think I would use the VOR/Loc/Glideslope functionality much. Switching to the 635 not only saved me about $1,000, but the unit is 0.8 lbs lighter and I probably saved another several pounds of antennas and wiring (not to mention hours of time that I would have spent hooking up the additional antennas).
