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? eepwallA:

Have you got a build thread we can follow along with?

Unfortunately, no. Figured with the excellent ones on here already, none was needed.

Could there be fault with the radio?

The terminal wire that you connect to #11 on the 44 pin main connector from the old multi-media module seems to be locked in and you can see it when you look at the end of the connector. So, I have no idea but maybe something bad with the radio? Is there any way to test that pin #11?

At this point, the AUX is enabled but thinks something is already plugged in, that is why it is always lit.

Here is is my comments on fixing the issue.

Thanks for the response. But, I think the wiring harness I purchased has everything spliced together. Unless something in there got messed up in shipping.

 

[StLouisCPhT]

I doubt it, since it is not tied into the harness assembled for the radio, screen and controls. Unless they have their harness off of Dhpt’s diagram on here. Even MVI did not have it wired correctly.

 

[PAChevyCruze]

Blakecary got the same harness and he said his works perfect. I just wonder if something got fried in the radio when I connected the wrong connectors. I connected the connector to one of the temp. control module ones. Dont ask! :banghead: LOL

 

[StLouisCPhT]

Uhhhhhh..... yeah...... ummmmmm.......

Ooops?

I don't know so much about the radio as maybe the wiring itself. I would still test things by making 4 jumper wires for the ones I referenced above on the PDIM connector, just to rule that out. Also, make certain that BlakeCary actually had a pdim in his vehicle (I can't remember if I ever saw them say anything about it). The wiring is different if one didn't come with the vehicle.

Question: Is the cable from the aux port going directly to the MyLink? IIRC, in some of the "base" radio setups, it went to another box first (PDIM). With the MyLink, it goes direct and the PDIM should be removed.

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.

Here is the wiring diagram for the aux plug in the mylink system.

 

[BlakeCary]

My CD player also says Error when I start my car, but I havent listened to a CD in a long time so that doesnt matter to me. Not worth ripping it all apart again to see if the ribbon is improperly installed.

As Far as the 3.5mm AUX. I did have a PDIM, that was just unplugged and removed.

Did you make sure that you put it in the right slot?

 

[BlakeCary]

"On the old multi-media module"? Did you plug the orange wire in from the NEW harness to the RADIO MAIN BIG CONNECTOR (with the lever lock) in back of the radio?

I PM'd you.

Unfortunately, no. Figured with the excellent ones on here already, none was needed.

Thanks for that wiring diagram, dhpnet. That should come in handy.

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.

I did disconnect the connector that plugs into the original media module and the AUX symbol was still lite up.

Blakecary: yep. #11 slot on the big 44 pin connector.

It goes from the cable that connected to the PDIM to the radio 44 pin plug. You remove the PDIM.

 

[dhpnet]

I am not sure what happens if you completely remove the PDIM. The PDIM communicates with the Body Control Module (BCM) over the LAN. I don't know if the BCM will recognize that the PDIM is missing. The BCM also communicates with the radio and might be sending a strange signal that is confusing the radio because the PDIM is missing. I don't know if that's possible, but it's a theory.

If I was troubleshooting this, I would probably disconnect pin 11 directly from the X1 connector on the radio - I would literally remove pin 11 from the connector. If there is a short somewhere in the wiring, it could cause the aux port to be active. You could also use an ohm meter and see if there is continuity between pin 11 and ground.

If that didn't fix the problem then I would reconnect the PDIM to the LAN to see if it makes a difference. If neither of those fix the problem, then I would assume the radio is the problem and find a different one to test.

 

[PAChevyCruze]

But if the BCM would see the PDIM was missing, the USB wouldnt work either, correct? That works fine.

I just bought a basic MyLink off eBay to test to see if the radio I have is bad.

 

[StLouisCPhT]

1) With a proper wiring harness upgrade kit, the USB plug is connected directly to the radio by the built in USB port on the back, bypassing the pdim module.

2) The bcm doesn’t care if the pdim is there or not. The radio does care however.

1) True. The kit included the USB cable to plug into the back of the radio and into the USB cable at the PDIM.

2)I dont think it has to do with the BCM. BlakeCary has the same exact harness and removed the PDIM, as the instructions say and his works perfect. Unless it's like the fog light issue with a certain year having to be "turned on".
