Xc70 refuses to play cd's cd error message

If the radio was not originally built to play MP3 format, then no. Unless the manufacturer has an update for the player's software/firmware (which I doubt they bother with) it will be impossible.

try running a laser cleaner disc, try a different CD

There is a major difference between the way a DVD is formatted and used and the way a CD is formatted and used. For that matter there is a major difference in the way these are manufactured. There is nothing wrong with your CD player. Try burning your disk to CD-R media and make sure you close the sessions instead of DVD-r media.

It will only play burnt audio CD's. No WMA, WAV or MP3.

its very likley the cd is fulty,, if its been left in the sun or it got hot some home burnt cd's dont play very well in car players,, try putting a cd head cleaner in the player but if it still refuses to play this cd try another cd that will play in your home player,, if it wont play that one its likley the lazer could have lost a bit of power in the car's cd unit

Check two items, chassey grounds by battery, transmission and starter. Also, check to make sure the alternator is providing enough voltage, should be around 14 amps. Had a similar problem with my 2002 XC70, replacing the alternator fixed it! I used the Car Talk website to find a good local mechanic vs. the stealer.

Is it a at home burned CD if so the CD player does not have the program capability for that format. If it is a CD you purchased and it still says error your CD player may need work of replaced. Could try a laser cleaner from any audio store.

is it a cd-r. some factory car stereos will not play a recorded cd. try a factory cd.

Most new car-stereo's don't have an "oldschool" CD-drive, but really a CD-ROM drive; meaning that they won't (properly) read and/or play copy-protected CDs.

Most CD protections are specially designed not to work in CD-ROM drives to prevent copying. As a side-effect most of those protected CDs won't work in car-stereo's.

Try a CD without copy-protection (like an homemade audio CD using burning software on your computer) and see it that works ?

In case that doesn't work either, your car's CD-drive is probably broken ...

it sound to me like the issue is not with the player, but with how the cd's were burned.  Make sure you are closing the seesion and that you are burning an audio cd and not an audio data cd.
