Looking to buy a Q7 3.6 premium. Currently a Sirius satellite customer. What does the "satellite radio preparation" mean versus getting the actual satellite radio as an added option?

Thanks!

check the costs, but it usually costs more to add it then to get it as a feature. basically when they add it they have to take your car apart again. call your dealer and ask the parts or service how much it is to add a satelite radio to your car. tell them you have the car already. they might have some cars that dont have the wireing harness for satelite radio
