AVIC-ZH77 series Carrozzeria navigation system 16P power wiring. It's surprisingly expensive to buy new. I am selling products that seem to be usable without any problems, especially used ones, so I think you can use them with confidence. If you want multiple items, please feel free to contact us. Navigation Audio Coupler *Used item* If an electro tap was originally attached, it has been removed before listing, so there may be parts of the wiring where the vinyl is exposed. We recommend repairing it with vinyl tape or similar before use. We do not ship on weekends and holidays. *Shipped by regular mail, so there is no tracking number and it will take some time for the product to arrive.*
