Bob somehow got the crazy idea in his head that when he changed the battery in his Jeep Liberty, the factory-installed 6-CD changer would not stop working. He and other Chrysler vehicle owners should have known better. Of course their stereos, made by Chrysler part supplier Mopar, couldn’t handle a battery change. Since no one has any idea how to fix this issue, Bob had the choice to get the same system replaced for only $575, or go out and buy a significantly nicer aftermarket stereo for a lot less money. Hmm, what to do?
