Has anyone else had problems with the sterio in the aveo? I am getting error codes and just wont play correct. I have 33k miles on it so still under the factory warr. I am thinking of putting a aftermarket rig in but can not find the adaptor for the head unit. anyone out there know where I can get a adaptor, also what is needed for the wiring kit? I replaced the unit in my chevy silverado but it needed an expensive 80$ wire kit becasue of all the bells and things that go through the radio.
