I recall years ago, you could buy a device that plugged into any car
radio that played cassettes. The thing was pushed into the casette
opening, and a wire which is part of it, could be connected to any other
audio source.

But what about car radios that have a CD player. Is there a similar
device that can be pushed into the CD opening to allow another audio
source to be played, such as a MP3 player?


You can pick up a MP3 input FM transmitter for a few $ (dealextreme or
?) and just use the FM radio.
That's been suggested several times and it has been noted that the
sound quality is often poor and when travelling younkeep having to
change frequencies to avoid interference from strong local stations.
