Anybody know anything about what it would take to convert a 05 s-80 with top of the line radio (I think it is called the 850 ) to one of the new Volvo radios that have satellite. My current radio has a SAT portion in it. The dealer says it can be done but wants to charge $1000. I would think there is some kind of conversion kit as they say they dont need to install a whole new radio, they say it can just be converted with the radio that is there. Any info would be appreciated. Thanks
John
