Garmin GTN 650

I purchased a new GTN 650 in February from gulfcoast avionics which includes the installation tray and factory wire harness that they built for warranty purposes. I ended up not installing the unit (had a mishap in my mooney and the plane is now at the scrap yard and not needing the 650) and am now putting it up for sale. I also have a used WAAS Garmin antenna to go with it. Everything is new in the box as I received it. I also purchased the USA base maps and I know there is some data included that allows you to do the initial updates from Garmin. Asking price is $7000.00
