I just bought an 07 s80 today and I have spent the better part of 2hrs trying to get the garage door opener to work. For some reason I was not given a manual for this car, so I have resorted to looking online for instructions. I have found a couple of different methods, and I have tried all of them in every way possible and I cannot seem to get it to work. Is there something that I might be missing or something that is commonly done wrong? Thanks.
