Ive got the MP3 6 disc CD changer head unit out of my totaled 04. I bought it a few months after owning the truck and it worked great for me. I just took it ouf of the truck before it was towed away because i didnt know if i would need it when i bought the next one. Well, my new 09 already can do what this one does and more so im selling this one. It worked great for me, the only thing it did was it would RARELY take two tries to get it to load a disc. It was very rare, but for full disclosure i felt i should mention that. It never ever had a problem playing, displaying text, shuffling discs or ejecting anything.
I have it for sale on Craigslist locally, but my asking price here is a healthy chunk less. I prefer local pick up as i heard these things are sensitive to shipping.
