For those of us who value their privacy and prefer not to participate in forced UConnect OTA updates, I have developed a single that effectively blocks all cell comms, inbound and outbound.

NAV and Cell are separate systems and have separate antennae. Blocking cell comms does NOT interfere with NAV. There is also some confusion about Performance Pages. This mod does NOT disable PP. If you have them, you keep them.

In the first month, I experienced 1 bar, 1G bleed. After that, zero. I have had zero cell comms, for a couple of years. Zero issues. Several dealer visits. No problem. You will get a nag screen that you can ignore and it will go away, or you can simply press OK and it will disappear, for the duration of that key cycle.

Things you need:

5 min epoxy

FAKRA D connector (cell comm)

10k (10,000) ohm 7 watt resistor, wire wound

3" square of copper Faraday fabric

1/2" diameter weatherproof shrink tube. About 2" long.

Heat gun, or lighter (to shrink the tubing over the end product).

Lay everything out, end to end, so you get an idea of how this goes together.



Cut down 1 lead, of the resistor and solder it into the signal pin.



Insert the signal pin and resistor, into the connector and solder the other resistor lead to the connector shield.



No picture, but at this point, epoxy the center resistor lead I side the metal FAKRA housing, so it doesn't bend and short.

Once the epoxy is dry (about 15 min), fold your Faraday cloth into a triangle.



Wrap the resistor tightly and slip the shrink tubing over and heat. You will have a little bit beyond the end of the resistor. While hot, pinch this closed.

NOTE: You will have extra Faraday cloth, beyond the resistor. Fold that over, before installing the shrink tubing.

With the car OFF, remove the screen and radio module, behind it.

Unplug the FAKRA D connector (same color) and ugh in your dongle.

Re-assemble radio and screen.

Enjoy your privacy.

Yes, the resistor shown is not 10k. Just wanted to get this out there, for you guys.
