According to Apple, over 90 percent of new cars retailed in the United States are equipped with iPod connectivity.
The iPod has become such a popular device, that many car stereos are now furnished with a 30-pin dock connector cable in order to link to the portable media player.
But this built-in compatibility is not essential for connecting your iPod to your car stereo. In fact, there are numerous options for integrating your iPod with your car.
Recently manufactured vehicles can support an iPod connection through an auxiliary input.
And FM transmitters can be used to stream your iPod's audio files through an FM frequency. iPods can even be connected to much older car stereos with the use of a tape adapter. Connect an iPod to a Car Stereo Through the Auxiliary Input
Insert an extension cable with 3.5 mm stereo connectors on each end into the headphone output of your iPod. Insert the other end of the 3.5 mm stereo connector cable into your car stereo system's auxiliary input. Press the "Aux" button on your car stereo. Turn on your iPod and select media to play. The stereo will now stream audio from your iPod. b> Connect an iPod to a Car Stereo With an FM Transmitter
Insert the FM transmitter into the 30-pin dock connector of your iPod. Turn on your iPod to activate the FM transmitter. Select the FM frequency you want your device to stream audio to on your car stereo. Turn on the car stereo and tune it to the same FM frequency as the FM transmitter attached to your iPod. The stereo will now stream audio from your iPod. b> Connect an iPod to a Car Stereo With a Cassette Adapter
