This is a TV canceler compatible with Mazda Connect. Model number is UTV404P. Easy installation, just plug it in between the navigation connectors. I am selling it because I changed cars, and it has been tested and confirmed to work. Since I installed it by pushing it into the back of the navigation system, the top cover of the main unit is slightly dented, but there are no problems with its operation. - Product Name: TV Canceler - Compatible Vehicles: Mazda vehicles This product is discontinued, so if you own a compatible car, please take this opportunity.
