hey everyone I just joined here and have a 99 S80, I have had no major Problems with the car so far. I was thinking of upgrading the stereo to aftermarket with sirus controls, but after things I have researched online and elsewhere I do not know if I can do this. does anyone know about aftermarket audio installiation? oh, I also have a nav system and do not know if this is conneted to the radio?
thanks

 

If you have the voice option then I think it is.If not then it should not be connected.
If you install an aftermarket radio then you will need the dealer to install software to remove the factory radio programming in the car.
The radio is part of the network of the car.If you just remone it and install the aftermarket radio it might mess with the computers.
