I remember a time when portable CD players were becoming popular and in-car cd players were considered a luxury item and not standard fair (yeah I'm that old) and I would use a tape adapter to connect my cd player to play through my car speakers. Today of course we have mp3 players that have essentially replaced those portable cd players, and now we also find cd players standard in our cars.

Some car stereos have a line input for connecting your mp3 player and some of the higher end ones even feature a USB port or even a memory card slot, but those are more high end offerings and we're left we having to either upgrade or find an inexpensive way to connect our mp3 players to take our music with us.
