A friend of mine got a Saturn Vue recently. He's inside his dash playing around with various things so he can get his amateur radio gear hooked up as it was in the previous car anyway, so I asked him if he could add RCA inputs to the jack panel he's adding.

The radio has no obvious inputs, but I have no idea if the harness has something he can tap... because I can't find out a damn thing about it.

Any suggestions for getting info about this factory stereo? (3 pictures )
