I have the same issue with mine. I don't particularly care for the looks of aftermarket radios in our cars, but I think I am going to swap it out anyways...not to mention, I want an ipod hookup in it as well.

 

i got rid of mine 2 weeks after i bought my car.. they are such crap, ate 2 cd's when i left the dealership haha. aftermarket ftw

 

mine did that for the 2 years i owned it, i just would hit the face of the cd player lightly and it would change. it worked for me for 2 years. to remove the disks i just kept a pair of twezers and would help them come out.

 

Go with a double din headunit.....They will cost alittle extra but look alot better then a single din headunit. They still make double din headunits without having to do a indash screen, but will generally cost about the same as an cheap DD indash screen....IMO the double din units will give it more of a factory look anyways.
