I have confirmed that it works without any problems. This is a TV canceler that was installed on an AGH30W Alphard 30 Series late model. I removed it because I am installing a different kit this time. There are scratches because the power was taken from a wiring split. The connector seals are dirty if removed, so I have left them as they are. There are no instructions. The vehicles that are compatible with TTS-41 are listed on the following website: http://www.j-e-s.co.jp/tv_folder/down/Available_tv_v01.pdf Thank you.
