i have a ford, or sony 10 disc in the trunk i cant remember and it works and cycles through the cd's it just wont play any of them.
I have a Sony MP3 changer in my trunk. If the power plug comes loose intermittenly the player will shut off then come back on. When it comes back on it automatically scans all the CD's in the Magazine. It will do this everytime the power cuts off and comes back on. (only the power to the changer not the rest of the factory system.
