3. They shut mine off 30 days after is was reported that the car was sold.. so.. 1 month.
I called the phone number that popped up, becuase a month seemed too short, I tought we got 3 months. Turns out...We DO! The month is for the dealerships test drive's and like you said, once it's reported sold, it goes off...but...audi set us up with a free 3month trial, all you have to do is call and they will give it to you free. Took 3 minutes.
(i'm gonna turn this issue into it's own thread in the General forum so everyone knows)
