This is a used AM FM 6 Disc CD player radio receiver for a 2001-2004 Ford Explorer. We purchased this from LKQ from a low mileage Explorer many years ago for a customer who never came to pick it up and by the time we gave up waiting it was too late to send it back to LKQ so it's been sitting in our stock since. It was guaranteed tested and good when we purchased it from LKQ then but we have no way to test it now so we can only relay what we know about it. Sold as is. Part number on the back is 1L2F-18C815-BD. It looks to be in excellent condition.
