interesting, I got a changer on eBay and once I hooked it up, the from closed and won't allow cd in at all, like its locked.I have successfully taken the deck apart and put back together. Unfortunately my deck error was a result of a plastic spindle breaking. This is why the CD would not eject. I was able to retrieve my CD, but the deck is toast. I do have it if somewhere if anyone needs parts to solve a different problem. I also have a good single CD player that a recycling yard sold me as a 6 CD Player and would not take it back (because it was an electronic item). If looking for a fix, recycling yards could be an answer at less than $745 but make sure you get the correct unit. I ended up with one from a 2006 C70 and it works perfectly in my 2005 S40 without any reprogramming. The second time I made sure the part numbers matched before I paid for it and did not go just on the yard person's word!
There is a chance that the unit you purchased off of eBay is broken (assuming it has matching part numbers). After retrieving my CD, I reinstalled my original unit until I was able to get the replacement 6 CD Player. However with the broken plastic spindle, it would not load any CD's. I would not get a "Deck Error' message since there were no CD's in the player.
