I have an 05 A8L W12 and would like to switch out my XM module for a Sirius one. Or I would like to just buy a Sirius module that will work in my car. Thanks.

Also does anyone know the model number I need for the sirius module for the A8L W12? In case I find one somewhere online for sale. I think I am correct in remembering there are different sirius modules depending on the car right?

are you trying to sell the xm tuner? do you have the part number on it? if it ends with E, i'm interested in buying it.
