I wanted to know if it is possible to get bluetooth installed on a 2007 S80 after I bought the car. Also, is the bluetooth module the same blue device that gets mounted somewhere on the instrument panel, etc., or is it integrated into the car like Acuras where the Caller ID and stuff show up on the LCDs next to the tachometer and speedometer? Lastly, about how much would it cost to get the unit itself where I install it myself?
