This is a Nissan genuine memory navigation system, model MP314D-W. The price will be reduced automatically every day. Please bid when the price reaches your desired amount. I have confirmed the operation of the navigation, CD, DVD, digital terrestrial TV, AM/FM radio, SD, USB, Bluetooth, touch panel, and monitor opening/closing on a desk. I have not checked all functions, so there may be oversights. There is a scratch on the monitor, in the upper left corner. It becomes unnoticeable when the power is on. This time, I have purchased new TV antenna wiring and films, which are included. They are a set of 4. The map data is from 2017. Serial number: NLTM038908JP The label on the back says Pioneer. If you have forgotten, please try initializing it yourself. You can restore it to the factory default settings. I will try to initialize it before shipping.
