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
radio. (Since the radio has a CD changer jack that is not in use, and
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.

I'd say it depends on the capabilities of this mysterious "adaptor".
What does it claim?
