This is a circa-2008 4' open array. Not sure of the model number as the nameplate is worn off. The radar worked fine until I removed it before covid for a change to Garmin but I cannot guarantee it. The radar is certainly compatible with E120 and earlier-based systems. I'm not real interested in trying to ship the unit so someone in the mid-atlantic (VA/MD) I can rendezvous with for a transfer would be ideal. PM me if interested.
