I haven't taken my radio out yet ... In another thread I'm trying to find an adapter that doesn't need me to wire anything in myself. Anyway I wondered, the adapter I just found looks like it plugs into 1 in the image above. I don't have steering controls so I don't think I'd plug anything into 2. Is the grey socket on the right as we look at it used? Adapter I found doesn't seem to have anything for that. Obviously the left is the aerial. Thanks 🙂
