Dealer installed aux jack for ipod in my x3.  Unfortunately installed into AUX, which means only volume control on steering wheel/radio works.  Not next selection/previous selection.  I thought it could be installed as 'CD Changer' in which case I would get volume and next selection functions.  does anyone know if it can be wired into something other than aux, or how the next/previous function could be activated.  I have the std radio, no cd changer currently installed
thanks
