I have switched to Garmin's G3X Touch screens and I have a GDU 370 for sale. I am asking $850usd and I will ship. This 370 is NIB. It has never been turned on or energized. It has only been briefly installed in my panel to check for fit and clearance. The installation kit is included but the connection kit is not included as I have already used this kit in my wiring harness. This connection kit currently lists for $68usd at ACS. Email or PM me for further details and/or photos. Thanks for looking.
