He doesnt think it has the Bose but there is a small stock amp mounted to the top of the trunk
He doesnt care if he looses the use of his steering wheel controls but wants to keep his door chimes
He can use the same one I used, a Scosche GMSR09. It can be had for about $50 at Sonic Electronics. He'll retain his chimes but steering wheel controls would be lost. Our cars don't come with Bose systems.
