This is a coupler needed when installing aftermarket parts on Subaru vehicles. They are surprisingly expensive when purchased new. I am selling items that seem perfectly usable even as used goods, so I believe you can use them with confidence. I can accommodate multiple requests, so please feel free to inquire. Navigation Audio Coupler *Used item* If an electro tap was originally attached, I have removed it before listing. Therefore, there may be exposed wiring where the vinyl has been stripped. I recommend repairing it with vinyl tape or the like before use. Shipping is not available on weekends and holidays. *Shipped via regular mail, so there is no tracking number and it will take some time for the product to arrive.*
