I have been posting in the WJ forums about this, but figured this section may have more people who know what to do.
I have been trying to add an AUX port to my '04 GC.
thread, there is a way to do it by tapping into pins 1 and 6 on the CD changer harness.
I do not have the harness or a CD Changer, but I have found a way to connect the wires to those two pins 1 and 6 (audio in left and right).
Anway, I have connected pins 1 and 6 to the left and right outputs of a 3.5mm phone jack. I have also connected pin 2 (ground) to the ground of the jack.
However, when I turn on the radio, it will not switch to the CD changer mode pushing the Mode button. I have made sure the mp3 player was playing while doing this so that there would be an audio signal on the wiring, but apparently the radio does not have the capability of detecting audio signal coming in to it's audio in pins.
Does anyone know how I can trick the radio into thinking there is a CD changer, or to make it 'aware' that there is an audio signal coming in to the audio in pins so that it will switch over to the 'CD changer' setting?
In viewing the pinout diagram from WJjeeps.com (posted below), the only thing I can think of is that maybe it needs a signal on the PCI bus?
would jumping pin 14 on the radio harness to pin 4 on the CD changer pins do this? I don't want to destroy the radio or short something out or anything.
Any help is appreciated!
