I want to do a car PC to use in my 04 GMC Sierra with the factory BOSE system with built in amp and sub. My truck also has XM and the On Star. I want to use it to play a big list of MP3's and to monitor my truck via my tuning software.
How can I do this with keeping the bose amp and sub, and my on star and my XM radio.?? Oh, and I want to be able to keep my wheel controls too?
