I am getting the winter blues for sure. Its almost spring but my car is still covered up since the roads are crap. I installed a Valentine One radar detector under my uConnect mirror using a Blendmount and Invisicord. Here are the steps I used. The most helpful section will probably be the pinout of the wires since I was not able to find anything that showed the wires I have on my uConnect mirror plug.
First, get in on the passenger side of the car. Turn the mirror and you will see a small door.
Open the door
Unplug the connector behind the door and this is what you will see
Plug in the RJ11 cord from Invisicord. The yellow jacketed wire goes to the black with red striped wire and the black jacketed wire goes to the solid black wire as shown here:
Then plug the connector back into the mirror and close the door. Be sure not to pinch the RJ11 cord.
Next, install the blendmount. I ordered the blendmount with hinge because the mirror has a recessed stem. The part number is BV1-2001. The instructions that come with the unit are straightforward. Here is a picture that shows half the bracket unscrewed so I could fit the unit around the rear view mirror stem.
Finally, slide the Valentine one onto the Blendmount and plug in the RJ11 cord.
The uConnect Mirror harness may not look like yours but I have a 2010 Challenger SRT8 with the microphone in the mirror. Here is the pinout from Dodge.
Using 8 for ground and 13 for positive works perfectly and allows for switched power when the ignition is in the ON position only, not accessory.
