Yah honestly once that Mach head unit starts giving you trouble it's tough to get it working 100% again.
Same thing happened to mine last year. I tore that sonofab*tch apart twice trying to get it to load/eject cd's again and the end results were 4 leftover screws that I had no idea where they went
My head unit still works, so I can still use my Ipod dock but the disc changer doesn't..I'm too cheap to upgrade or buy a replacement so I just deal with it...besides I don't really use cd's anymore anyways.
...and don't feel bad, this is a common problem with these units...since 02 they have been jamming up in mustangs lol.
