With an MP3 compatible in car CD player, you can enjoy up to 10 hours of music in your car without ever changing a CD! MP3 players play compressed MP3 files from data CDs, as well as playing regular audio CDs. MP3 compatible in car CD players allow you to use disks you have copied your favourite music tracks onto and listen to all of your favourite music without having to keep changing CDs.

Ipod compatible CD players allow you to connect an Ipod MP3 player to your CD player. Some kits, including the JVC and Blaupunkt units even allow you to control your IPOD from your car MP3 player.
