I did not take pics but will pull door panel off this weekend and take a couple pictures and monkey around with it and if I don't get it right I'll post up the pics.

As far as it having been a Bose, I am pretty sure it is the original head unit that is almost a double din size that has the cassete player and graphic eq along with steering wheel controls. If it's not original it fooled me. Also none of the speaker grills say Bose and the 12 disc changer in the trunk is an ac-delco unit that works with the head unit.

Thanks!
