You might remember, “way back when”, the old tape adapter which was used in a car with a portable CD player to play CD’s through the car’s stereo. Today, there are fancy add-ons you can purchase for your portable MP3 players which broadcast music through an FM channel which you can tune to on your car.

While these devices seem to work ok, they are a bit on the pricey side (~$20), in my opinion. So instead, if your car has a tape player, consider using the old tape adapter on your MP3 player. These can be had very cheap, as I got mine for $3, and work great. Simply plug in the adapter to the headphone jack and then pop it in your tape player.
