Thanks buddy,
I done exactly the same, it works perfectly and the fader / balance controls all work as expected, I just lost some volume. My other half can't tell the difference but I can!
Oh well, I can be arsed to pull it all out again at this weekend
Btw, did your ariel jack slot into the Alpine ok? The Nissan ariel jack is too wide for my (Alpine) head unit so I need to get a little adaptor. My other half was well impressed. So you've lost the bluetooth control for the phone? yep. so you've lost the radio? Yep, but only for now....
