I just bought an 2006 range rover with the entertainment package and I tried hooking up my ipod with an auxilary wire to the back of the center console and the volume is extremely low. I turned up the volume all the way on the ipod and all the way on the head unit and still very low volume. Has anyone experienced this or can help me in any way? I have tried several wires and all have the same result

I thank you in advance
