Hi all,
In this thread, I include all wiring needed to replace the radio and retain almost every feature of the car and how to wire them.
Standard disclaimer:
I'm not responsible if you screw up something. This info is given out of good will, to the best of my knowledge. I'm not a profesionnal, only an amateur (with 23 years of mobile sound system background). Don't come to cry if you burn your car down and your wife leaves with the kid :wink2:
Known features that won't work with aftermarket radio:
- Display above the radio will not display audio track info or radio station playing. It just stays blank on the screen that would display radio stuff. Nothing's broken on the other pages of this display
- Display above the radio will not display Weather info (If you had Sirius subscription). The Weather page just don't appear anymore. Nothing's broken on the other pages of this display
- The time won't auto-set (battery removed) or auto-update (Daylight TimeSaving) anymore. This feature comes with the XM/Sirius tuner.
- You can't change car parameters with the radio anymore (lights timer, distance unit, buzzer volume, etc). You can use the steering wheel buttons on the bottom left as usual. It's just a little less convenient but it works well. Not a deal breaker.
- Volume adjustment with Vehicule Speed probably won't work. It depends on your headunit and finding the right wire to plug in. My new headunit don't have this feature.

Removing OEM headunit
To remove the radio, it's very straight foward:
1- Insert flathead screw driver between Vent and soft dash board at the botton of the vent. Using the soft material will prevent any damage to the dashboard part. Repeat for both vents on each side of radio
2- Remove the top part above the radio. You can just yank it toward the back of the car or pry it like on the 2nd picture
3- Remove the 4 screws. No picture of this. Next you can pull the radio toward the back of car. It is clipped on in addition to the 4 screws.
4- Disconnect all the connectors. They all have a clip to be pushed to be removed, even the USB one.
Connect headunit Dimmer
If you want to connect the illumination wire so your new headunit retains the dimmer feature, you will need to remove the HVAC controls. I have a Limited model with auto HVAC, but I would guess they are all mount the same way.
1- remove the radio as per the instructions above
2 - 3rd picture is a view from the radio hole, looking downward toward the HVAC controls. I circled the pins that hold the HVAC controls. You can either push on them from behind or try to pull from the front. The top is easy to unclip (black clips), the bottom is held with blue clips and they are hard to pull
3- Unclip the wire harness.
4- The wire you need to tap into is the 2nd from the right, bottom row, the orange one. It's the picture with a needle inserted. What I found easiest is to remove the pin from the harness and tap on it, tape the wires toghether tightly, then insert back in harness and reclip the bottom
5- To remove pin, disengage each side of the harness so the bottom pops loose. Then insert needle above pin and lift the plastic tab, while gently pullin on the wire.

Connect headunit to parking brake
If you want to connect the parking brake wire, it's on the 28 pins connector behind the radio. It's pin #15. 1st on the left, bottom row. Gray wire.

New location for USB and AUX in
For the USB and AUX in of the new radio, I just passed them throught the center console compartment below the HVAC. There is a hole to hold a light but it's empty. With the radio removed, you can use a file to enlarge the hole just a little bit and fish your wires in this place. I prefer to have the USB plug there as opposed to the OEM place.
