There is a pigtail on the part (female aux connector) that is about 24 inches long so that you can route the wire to a location that's inside of the glove box and mount the aux port.



When the aux port is installed, the MODE button on the radio will present AUX as one of the inputs. Successive presses of the MODE button will roll around the input choices of AM, FM, CD, and AUX. The port works good, just use any aux cable to plug into your headphone jack on your phone, and the other end into the aux port that you just installed into your car.



I have an '05, with the MK4 Nav System. There are two aux ports that can be plugged in, one has a micro-mini 2-pin connector, the other has a mini. Except for the connectors being different sizes, the ports are identical. The nav display will see the new aux port as soon as it is connected.The cable is on eBay, and comes from a dealership out of San Francisco. I recall the cost to be $40-ish.
