I recently got a new 2010 Malibu, and am trying to work out how I'm going to install a computer in it.

I would like to keep the radio, so I don't have to worry about getting an amplifier. Ideally, I would also like to have information display on the radio's screen, and have the buttons on the radio and the steering wheel control the computer as well.

I haven't found anything specifically for the 2010 Malibu, but for a 2009 Malibu, I found an iPod adapter that connects between the XM Radio module and the radio, shows the current song, and allows for control of the iPod from the radio. Could something like this be reverse engineered for a computer?

Any ideas on how something like this could be accomplished?
