Audio n Mp3 !!?

Hi!

i have a cd player in my car which plays audio cds, what i want using the same player to play Mp3.
Is there a software that can support this?
that is, it will be converting those file in Mp3 to audio file when they are in use ie. the software will be on front while the Mp3 file on the back so that the player will be tricked by the software.
or it possible for this to be done or to be developed?

thanks.
