Re: Does the XC90 CD deck play PC-made MP3 songs? (Rick_Auricchio)
You will need to try with your computer's particular CD-R drive and your particular CD-R discs (I would advise against using CD-RW media). As has been reported with many makes of in-car CD decks, on SOME occasions, the in-car deck simply won't recognize the disc.
On our 2005 XC90 with premium sound (in-dash 6 disc changer), we have only had one compilation CD out of about 25 that did not read. I re-burned the same tracks again from iTunes, settings to Burning, Audio Disk (NOT MP-3 or Data CD), and Preferred Speed Maximum Possible, and it worked fine.
Sometimes bad media (disc) or errors if written to a particular disc "too fast" can lead to it being unreadable. The manual provides a standard/spec for the CD-R media, but with that one exception, we have used standard Memorex and Maxell CD-R discs with success.
I think you need to burn them as audio CD's and not MP3'
