My new used car from 2005 has a CD that will not play an MP3 CD, but I
can buy an adapter that will add an AUX input and a USB input to the

this is designed for that shape of jack.)

Long after I ordered one for $18, it suddenly dawned on me that if it
can't play an MP3 CD, it won't be able to play an MP3 file from a
USB-connected flashdrive. That's true, is it not????


It's amazing how long it took me to think of this problem, at least a
week.

Are you talking about a specification of the player or an observed symptom?
Does the player play music CDs?
Have you cleaned the player lens?
Does your MP3 CD play in other players?
CD players are designed to ignore major flaws in the data stream
caused by dirt and scratches. Playing MP3s might not be that forgiving.

The automobile is a VERY hostile place for an optical drive.
It gets very hot and there's lots of plastic to outgas and land
on the laser system.


I bought a MP3 CD player for my car. Worked ok with pristine
CDs for about a year. Then it quit. I cleaned the lens system
and it worked for about another year. I gave up and plugged
a SD card into the slot and have been using that since.
The SD slot wouldn't play anything bigger than a 2GB card.
