An auxiliary input converter for the F-150 and other Ford "CAN-Bus" radios with the 'AUX' button!!
The PIE FRD04-AUX Auxiliary Input Converter connects to the Satellite/Rear Seat Entertainment (RSE) data port of many 2004-2008 Ford CAN-Bus factory radios (Please see Specific Vehicle Application List below), to create an external auxiliary input that you can then use to connect the audio from any external audio source, like the audio from an MP3 player, a portable DVD player, computer, video game, any audio device that has an audio output connector.
This auxiliary input converter connects to the 16-pin connector that is located on the back of the factory radio, shown in the image at right (Click image to see larger photo). Depending on what factory options your vehicle has, there could already be a factory wiring harness plugged into the 16-pin radio connector. The wiring harness that comes with this interface is designed with a 'Y' connector that allows you to reconnect the factory wiring harness, if so equipped, once the interface is installed, keeping all existing factory options functional. If there is no factory wiring harness plugged into the 16-pin connector, the 16-pin 'Y' harness will remain empty after installation.
With this device installed, you will have created an auxiliary audio input to your factory radio, which will now allow you to plug in any external audio source, like the audio from a portable MP3 player, satellite tuner, DVD player, or iPod, into the left & right RCA-type connectors (shown at left), and play the audio from that external audio device directly through your factory radio. This is a direct-connect device and NOT an FM Modulator. An FM modulator requires you to tune to an FM radio station in order to listen to the audio from the external audio device. This device does not work like that.

Great for leased vehicles, company cars and rental cars and vehicles.
