This 36 mile radar was a backup for the one on our boat. I took both of them to the Regional Furuno Repair Center in Vancouver, Washington on April 15, 2024 to be checked out and serviced. The bill is in the pictures. Since we are now in the process of selling the boat I don't need a spare anymore. The 12 volt plug in pig tail for display is missing. It got sent accidentally to boat in Mexico with other radar.
