This item was removed and stored when the vehicle was replaced. Due to long-term storage, there may be some deterioration over time. I have confirmed the indicator display, switching, and button operation. There are no manuals or instructions. Since I cannot confirm the actual operation, it is a junk item. Also, since it is a junk item, the overall condition is considered poor.
