just picked up a '04 A8L and want to install XM. Can someone tell me exactly what equipment and wiring I will need to purchase, and is this an install I can do myself. I'm not much of a DIY'er.

thanks.

 

Congratulations, I just bought an '04 as well! I also just had an XM receiver installed last week! Your car is pre-wired for either XM or Sirius. If you are in the Chicago area by chance, call Laurel Audi in Westmont. They charged me $330 including installation ($129 was labor). Another Audi dealer I called wanted $500 just for the receiver, plus another $129 for labor to install! Maybe other dealers are selling it for less as well.

I believe you could install it yourself. It mounts in the trunk on the left side, just remove the panel held in place by two plastic screws. You will need the receiver and mounting bracket from the dealer, but all the wires are already there and just plug into the receiver. The system will then work right through your MMI and steering wheel controls.

Good luck, and enjoy your awesome new car!

 

Local dealers want $550 plus $150 install. I picked up the xm tuner on ebay but i need some installation instructions if anyone can help
