5. Plug the wire harness connector into the CD changer port at the back of the
radio. Make sure it has a firm connection.

performance before re-assembling the dash. Insert USB pen drive or SD card
and switch on the Head Unit. Press the CD (or Disc/Mode/CDC/SOURCE/AUX)
button on the radio once or twice to switch to playback mode of the car adapter,
with the symbol of LED light being on. Depending on the car stereo type CDC,
EX, or CD01 will be displayed on the radio screen. Now the audio adapter will
run normally.

Important:
If the harness has a BLACK ground wire, please attach it to any metal part of the
head unit body; If the harness has a YELLOW power wire, please attach it to the
power of the car, which connects to the battery; If the harness has a RED ACC
wire, please attach it to the ACC signal of the car. It’s extremely important to attach
these cables to the right place otherwise the AUX Link car adapter will not work!
If the car already has a CD-changer plugged into the jack, the AUX Link adapter
can be connected in parallel through the splitter (Parallel Harness or MP3/CDC
Switch Cable will be provided).
For Fiat, Renault models, there are two black wires with metal ends (male+female)
that come along with CDC connector. If you experience any noise problems when
using the adapter, please make sure to hook up the two grounding wires with each
other.

the Peugeot/Citroen dealer the information on how to activate the CD Changer
function.

memorized point.
