This is a Carrozzeria car navigation remote control. It was included when I purchased the car navigation system. I didn't know when to use the remote control, so I kept it without opening it. Therefore, it is a completely unused item. Due to concerns about substitution, returns after purchase are not accepted. Please understand the above before purchasing. For reference, the navigation system I purchased is the carrozzeria AVIC-CQ912III 9V-inch HD/TV/DVD/CD/Bluetooth/USB/SD/Tuner AV integrated memory navigation. Please also check if the remote control is compatible with your navigation system. I will also include the batteries in the photos. As it is a precision instrument, it will be wrapped in bubble wrap and shipped.
