Vellfire 30 Series Rear Switch Remote Control Kit This kit allows you to operate the air conditioning, roof color illumination, sunroof, and other switches from your seat. This product was used for only one day after installation. I found it convenient to be able to operate the remote control without getting up while driving, but the roof color illumination needed to be operated every time the engine was started, which was unpopular with my family, so I removed it and stored it. The remote control operation of the air conditioner, roof illumination, and sunroof was possible until it was removed. Please participate only if you understand that this is a used item. Thank you.
