Aux-In

Your Car Kracker has to be powered up and connected to the car whenever you want to use Aux-input. You can power it up with 4xAA's batteries or connect it to a USB car charger.

Not all head units need CD changer emulation - some have a second set of audio connectors just for Aux-input. In that case, you just need to construct a cable.

If you boot up the Car Kracker without holding a button and without an SD card, you'll enter Audio Aux-In mode. This mode lets you connect any MP3 player or even bluetooth player and listen to it on your stereo. Here's how to set it up;The 6-pin header in the trunk connects to an analog audio input to your stereo. Unfortunately, the stereo won't tune into that audio input unless it thinks there's a CD changer connected in your car.The Car Kracker solves that problem by pretending to be a CD changer. Your stereo will think there's a CD changer and amplify whatever signal is coming in the analog in line. Here's how to set it up;With the Car Kracker connected to your car, turn it on without inserting an SD card. After a few moments, it will be CD changer emulation mode. Whatever audio signals come in through the CD changer audio connection will be played on your stereo.You can connect whatever audio source directly to the 6-pin header in the trunk, although that can be inconvenient. You can use a Bluetooth A2DP adapter and play audio from your cell phone over bluetooth, or you can connect your audio source directly to your stereo.

First the passenger side panel, then the middle panel;and remove the two screws holding in the stereo;Remove the connectors off the back and slide out the stereo;You'll want to connect your left channel, right channel, and ground to the pins on the bottom;You can run that cable out to the sunglasses box under the stereo or to the glove box.A few notes on Aux-In;
