This is a genuine Nissan MM312D-W wide memory navigation system. It was used in a 2012 Nissan Note until April 5, 2025, just recently. I am selling it because I replaced it with a navigation system from another company. The car's mileage is 68,000 km, so the navigation system wasn't used that much either. I don't know what year the map data is. The instruction manual is included. When I had it replaced at Autobacs, the front windshield antenna was messed up during removal, so please purchase a film antenna separately.
