I'm selling my:
Garmin CNX80 (VHF, VOR, Satnav GPS and remote transponder controls)
Garmin MX20 (Multifunction display)
Garmin GTX33 (remote transponder)
The units are still being used in my Impulse ultra light, but with the upcoming new leglislation in Europe which will make it mandatory to use 8,33 separated VHF comms, I need to replace them.
