2000 S80 Carputer install HELP!!
 

Hello everyone!
Heres my current situation, i own a 2000 S80 and the CD player crapped out on me. So me being the DIY type i decide i want to install an in-dash computer in place of the stock CD player. Ive been looking around for wiring diagrams or any help at all but couldn't find much! ANY suggestions would be GREATLY appreciated!
Thanks,
