Thanks to all for their comments. To be fair the instruction in the manual for adjusting the volume does say "where fitted", but I thought the XR6 may fit into that category. I went for the lux pac, side air bads, roof and sensors. If they asked me to pay extra for the sensors I could hear then I would have. Still, I will talk to my dealer and if he cant fix it then I will attempt to have the price of the option refunded. I will let you know how I go.
