My local audio shop gave me an adapter to plug into my stock green in-dash radio adapter and then into my Z1. Everyting works but my sound. I noticed my speaker wire colors are not the same as those at the stock radio conncetor. I tried every combo, even changed the pin locations on the adapter and still no sound! Guys, please help me out, I've been stuck with this all day, and I'm dead tired! lol. thanks for any help. :(
