If you own a car with a standard cassette player, for about $10 (at your local Wal-Mart) you can purchase a car cassette adapter. It looks like a cassette tape with a wired ¾ inch plug connected to it. Insertion into your cassette deck allows you to play your ipod through your car's speaker system at CD quality! On long trips, this is fantastic! You never have to change a CD or only hear the same 6 CD's over and over again! In fact, anything that can take a ¾ inch plug will work with this adapter, your kids mp3 player or even that movie they're glued to on their portable DVD player. Whatever device you choose, this inexpensive adapter gives you quality sound and, depending on the size of your ipod, music for days! The only drawback is the wire that goes from the cassette deck into the armrest. Plus, if your car doesn't have a standard outlet, you do have to remember to turn your ipod off when you get out of the car for the day. If you can get past that, this is a steal and a great alternative to spending money on a new car stereo with it's own ipod docking station!
Use with Portable DVD Player - Normally, the adapter's audio wire is plenty long, but if your cassette deck is too far from your DVD player you will need a short audio cable that is male on one end and female on the other. Plug the adapter's wire into the ‘female' end of the audio cable. Plug the male end of the audio cable into the ‘audio out' on your DVD player. Presto! Movie surround sound for your car or old school van!
