This isn't for my fusion (thankfully as I'm sure its much more expensive than the system I have thats broken) but for my parents lincoln navigator which is a 2001 model. They have an alpine 6 disc cd changer and its not working. It can be full of discs and it will say its empty. I tried replacing their battery for them and had a friend who's a bit of an audiophile take a look but no go. I've done some research and apparently these things cost about $150 to buy new but what about installer fees? They're trying to sell it so this could help a great deal.
