So here I managed to connect the box on my laguna. I thank those who have helped me even with false information about the connection! For the seller it is not even bother to ask them any information you see Google responds to translate the scheme. So I found the son of the connections on various forums because here I also think that the answers are finally approximate. For the product no complaints after connecting it works well. For remote controls there are no keys then it is stipulated in the description is the fault? It should anyway be better correct it. So to finish very good product and especially cheap compare a centralization to the manufacturer (brand) I do not know if the product is reliable over time but that your instantly. Voila I hope I can help myself.
