2007+ Audio Aux Pin Out

[asanelli]

Does anyone know the pin out for the audio aux headphone jack in the center console?

I want to try to integrate the aux function into a fully functioning usb interface that will provide and audio.

The connection should be a 4 pin connector with the following leads (ground, data+,data-,power). However I want to confirm this so i can integrate into a usb....

Does this help? It's from the EWD.

Yes that works.

You don't to have a legend for what the wires are?

I assume they are the following.

ALO: Data Low
ARO: Data High
ASGN:Ground
AUXO:Aux

Any thoughts??

What is the EWD?

Do you have a legend?

Do you have the info for a 5th gen?

EWD is Electrical Wiring Diagram, a factory service manual just for the entire electrical system.

Pretty sure they are Analog Left channel Out, Analog Right channel Out, Ground and Aux out. Unfortunately I don't know enough about this stuff in regards to 'data' signals.

The 4th manuals are all available online. I don't know about 5th gen stuff but they probably are.

Not sure what you are doing but keep in mind there is a signal wire that tells the head unit something is plugged in. I had one go bad and the HU wouldn't switch to aux. If you are modifying it in someway, you will need to trick it.
