This is a remote control for Alpine's drive recorder (dashcam), model number "DVR-C01W". It's a convenient optional item for operating the dashcam. Please confirm compatibility with your specific model. This is a spare I had, and it's "unused and new," unopened. It comes with a button battery, but I'm not sure if it still works, so the warranty only covers the remote control itself. It will be shipped via Mercari delivery with free shipping. I will take the utmost care in packaging, but there's still a possibility of unforeseen circumstances. In such cases, I apologize, but please coordinate with the shipping company. (The seller cannot provide compensation.) *Please read the notes on "free shipping" in my profile before purchasing. By purchasing, you are considered to have agreed to the terms.
