How to Connect GPS to an Auto Stereo
Many automotive GPS devices offer the ability to store and play audio-book and music files. If your GPS includes an FM transmitter or modulator, you can create a wireless connection between the GPS and your auto stereo. If your GPS does not include an FM transmitter or modulator, you can create a wired connection between the two devices with a standard audio cable.
