I have recently purchased a used 04 A8L and I would like to install XM radio. Do I have to go the dealer( about 500 bucks) or can any install shop put in. Where does the module hook in? Thank and eventually I will post a pic but the weather has sucked around here and the days are short. Thanks

It is a simple plug and play procedure that requires you to plug in 4 cables that are already prewired in your trunk. Open the comparment on the left side of your trunk where your NAV unit is located, and you will find 4 cables that need to be plugged into the XM receiver. Mount the bracket on two screws that are just behind the NAV unit and the XM receiver bolts right in. It is a 20 minute procedure if you have a 2005 or later. If you have a 2004 it needs to receive the free MMI upgrade at the dealer. Just check to see if your MMI display lists satellite as an option.

Thanks, that looks simple enough. When scroll through the MMI menu, there is an option for satellite radio so I assume I can get it after I activate the radio. Thanks again.

Do you know if this would be the same for a VW Phaeton with Nav. I assume that parts are simular.
