It actually pains me to do it, but I am trading in my 07 A3 for a 2011 Q5. I put 105,000 miles on my A3 and it has been an "incredible" vehicle!!! Now to my dilemma...I currently have the XM radio module in the A3 and the Q5 comes with a Sirius module. Does anyone know if the XM radio module in the A3 will be able to be put into the Q5? When I bought the A3 it had a sirius module and I was able to switch it out with no issue. If anyone can comment, it would be greatly appreciated!!!
