2013 Volkswagen Passat Retaining Factory 3.5 AUX Plug With Aftermarket Stereo

If you're going to be upgrading the factory stereo in a 2013 Volkswagen Passat, and replacing it with an aftermarket stereo. You will typically lose functionality of the factory 3.5 AUX input in the center consol, unless you integrate it. It's pretty easy, you will want to make sure the new aftermarket stereo have a AUX input on the rear. That way you will not see any wires running to the face of the stereo. 

The three AUX wires should be in a blue 12 pin harness, that is part of the main factory stereo harness.

The wire should be:

Left Positive - Yellow

Right Positive - Gray

Ground/Common - Green

Once you have identified your wires in the vehicles, you will want to identify the wires in the 3.5 AUX cable you will be using. After you do that connect the wires, plug in the 3.5 AUX to the back of the new stereo and you should be good to go...

Hope This Helps!
