WTF! 885 there but they never finished the job and made it highlight! Pure cheapness/laziness! Absolutely not the quality I, or anyone should expect from a major mfr. Obviously they don't give a crap!
Oh, c'mon. Next you'll want the Lie-O-Meter to show actual mpgs, right?

The one in the GT AWD is over 2 mpg off - in the optimistic direction, of course.

Tolerance of bad behavior is approval of bad behavior.

They promise you this then give you that...
Can I get my money back???

Whatever vehicle I first had with that fantastic option available resulted in many emails from them.

Eventually I got tired of them and called, telling the lady that I had no interest in Guardian. But there are so many great features available, she said. Like what, I asked.

Oh, you can find your car with Guardian, she said proudly. I told her that if I was so wasted that I couldn't find it, I have no business driving it. That ended all the emails for that particular vehicle.

I would've thought that after never having used the free introduction period on any vehicle they'd give up, but nooo.

Guardian is the problem we're all talking about, here.

Cooked up a fresh batch of D and H series cell blockers.

Shipped a few out, already.

MY15-MY17 only need D (purple). 100% blockage.

MY18+ can block comms on circuit D (purple) and H (pink), but the aircard still has cell authority, maybe from an onboard backup antenna. At least we can knock out 2 out of 3 comms.

So does MY17 need one or two blockers?
A previous post said 2.

Iirc, 17 is a transition year. Only sure way is to pull the radio, or figure out what radio you have.

I have a full set of satcomm and cell comm blockers (3). If you want dibs, send me a PM with your address. I can ship, tomorrow.

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.

Where are we able to purchase one of these & Im assuming it would work for a trackhawk as well?

Instructions are at the top, for DIY.

If you prefer, I can provide the blockers you need, for your TH. You will need pink and purple blockers, for this application.

Shoot me a PM and we will work it out.
