This unit has been sitting on a shelf for a very long time. It looks to be in good usable condition. The CD goes in and out fine. I did not hook any speakers to this. I’m not sure about its operation, but the XM button and the exhilarate button don’t change anything on the screen.maybe they have to have accessories to make them work. You would know better since you’re looking for this. I’ve never seen it installed in a car. I’m just bench powering it.
