Hi, just replaced the Bose head unit as it was useless, CD's jumping and the left speakers going on and off. I got the Bose ISO connector assy and modded the cable as per busters post, the problem is the Bluetooth and nav outputs are blasting out with the volume on 1, can't fault the music, its so good you can feel the woofer kicking you in back, all nav and Bluetooth volumes are on min, any idea's, cheers
