Is it now, not playing disc's that it used to play? If this is the case, the laser pick up either needs to be cleaned (with cleaning disc) or it needs to be replaced. If cleaning it does not help, the pick up is getting weak. When this happens, it will only play disc's with a high reflective surface. Store bought disc's have the best reflective surface. Burned disc's are not as good. Some burned disc's are better than others. The disc's with a blue or green data side are the highest reflective surface for burned disc's.

Sometimes the disc's can not be played because of the condition of the disc. If it has a lot of scratches on it, the player will have problems if those scratches are deep or if they are in the area of the disc that the TOC (table of contents) is written on the disc. Thate area of the disc is in the inner most area of the data side of the disc. The cd player must read it first, then it knows where to find all the songs and all the information for the songs.

Fingerprints are also a problem for cd players. A fingerprint will bend the light from the laser and make a disc unplayable or cause a lot of skipping.

The first thing to do is to clean your disc's. I use windex and a soft cloth like a bath towel. It cleans cd's and dvd's as good or better than any of the disc cleaning kits you can buy at a retail outlet.

Next, get a cleaning disc for the lens of the laser pick up. Run it for about 20 to 30 seconds and then take it out.

If these things do not help, you may just need the laser replaced. That usually runs about $125 or so depending on the rates of the shop you take it to.

I hope this helps and a Fixya rating would be appreciated for this free information.

Thanks, and let me know if you need any more help.

Do the cdx-4000x have a ipod plugin

No, not directly. Here is a link to Sony for your CDX-4000X Operating Instructions.
Belkin as well as many other companies make devices that plug into the ciggarette lighter and then into your iPod. There is an FM tuner controller than sends the music from the iPod to an FM station on your head unit. Belkin calls theirs a 'tunecast auto'. I believe it sells for about $30 USD.
