Of course, nothing ever goes smooth for me. lol
First, installed all the hardware and tested it. CD player doesnt work and must have been broke from the previous car. Oh well.
The AUX icon is on but no sound comes from the radio when I plug my player into it. USB works fine. Anyone have any idea as to why the AUX has no sound? Which wires send the sound from the AUX to the radio?
On the CD player, you can check to make sure you plugged the ribbon cable in correctly when you programmed the chip. That would make it not work.
On the Aux input. The Aux input plug in the center console needs to be wired directly to the radio. You should not have any of the wires from the PDIM connecting to the radio. You don't have to remove or unplug the PDIM. The Aux wires bypass it and go from the input plug to the radio directly.
Pin 11 on the large radio plug is the Aux detection signal. When you plug in a cable, it connects pin 11 to ground. If pin 11 is grounded then the radio thinks something is plugged into the aux port. If you think it is not connected correctly, disconnect pin 11 from the radio and see what happens.
Look at the drawing I created and you can see exactly which wires from the Aux plug connect to which wires on the radio.
Pin 4 on the aux plug is the right signal and goes to pin 10 on the large x1 radio plug
Pin 5 on the aux plug is the common (negative) wire and goes to pin 23 on the large x1 radio plug. This is connected to ground in the radio. It also connects to the same ground as the aux detection signal in the plug.
Pin 2 on the aux plug is the left signal and goes to pin 24 on the large x1 radio plug
Pin 1 on the aux plug is the Aux detection signal and goes to pin 11 on the large x1 radio plug
Pin 17 on the large x1 radio plug goes to the shield that covers the wire going to the Aux plug. It is just there to reduce noise. It does not connect to anything on the aux plug. It is just cut off right before the plug.
