Anyone here know anything about 6-disc changers?!?! My changer works when it wants to. It will work for a couple days and then wont work for a week. When it isnt working nothing even appears on the dash when I press "cd". I can sometimes get it to work when I unplug the cables to the actual changer and then replug them in hours later. Any ideas what the problem may be or is my changer garbage? thanks for any help/ideas.
