Good afternoon, I have a problem that I don't see a solution to. I have an Audi A3 8P with the factory BOSE system, with a Symphony II radio. I want to change radio to a Pioneer DMH-A240BT. It turns out that I have to buy adapters but I don't know which one to buy? I search and several adapters appear. I leave a photo of the radio and the connectors present in the car below.
