Brand new, unused item. This is an item that was included with the KENWOOD MDV-M911HDL. Connector type: VR-1 It is believed that this can be used with other manufacturers' navigation systems if they have the same connector. For example, Panasonic and Pioneer (Carrozzeria) navigation systems. I have confirmed that there were no issues with reception sensitivity when used with navigation systems that use the same connector, but please consider this as a guideline only. Also, please note that I cannot answer questions about compatibility with specific models.
