I just bought a 2004 GMC Denali Pics of the Denali
, its nothing like the M3 but it is amazing how it handles for a big truck and the turing radius is amazing. Well anyways the Denali has the XM satillite radio. I fell in love and would love to get it in my m3. I went to the BMW dealership and they said that they only have sirus (have an agreement with them) and it would be $1000 for the installation and a couple hundred a month for service. What should I do? Can I get the XM in the M3 without additional head units?
PS I have a stock stereo not the GPS
