Has anyone disabled telematics / LTE and GPS antennas?

[WILDHOBO]

Right. The suggestion that if you don't want to be monitored, you should buy an older Jeep is simple minded and ridiculous. There was no pre-telematics, pre-canbus Gladiator.

This tech isn't going away. So people need to figure out a way to disable it. Like I said above, I will be experimenting with disabling the LTE modem above the roll bar once its warm and I can remove the top to access it.

To each their own. I’m not a fan of dash lights and broken features after disconnecting antennas. Or warranty voids on your entire infotainment system.

I'm not a fan of any of that either. Which is why I'll try to disable it first by blocking or disconnecting the antenna. If the transceiver is on but its got no signal, then it won't throw any lights.

I don't see how any of this could impact any aspect of the infotainment system other than the LTE modem.

i'll repost this from another thread where i just posted this. I'm sure having all this great tech is just fine. As a net sec guy (sumdan) you should under stand this.

to throw gas on a fire, imagine a foreign country that has high tech abilities and they want to invade a place, sure is convenient to pay a few agency hacks to take over a car telemetry network and disable a few million cars and stop a population dead in it's tracks then it would be to stop them one at a time..... just saying. If gov'ts can hack into reactor sites what is stopping them from taking over a low security OEM server.

Please don't say these systems only broadcast and don't receive cause no one truly knows what these telemetry system in our jeeps are capable of.

Anyone remember when 911 happened and all GPS signals were cut off until they figured out what was going on?

not trying to be tin foil hat here, but I can guarantee someone has been paid big bucks to to make a action plan for this in the event of a problem.

To DCM's point unplugging the antenna would be the best way to stop receipt and broadcast of data and would be no different then being in the back wood with no towers around. The only draw back I could think is a the circuit is monitored and if the antenna is removed then a open circuit or change is voltage is flagged.

Here are a few white papers from Trend Micro a leading IT security outfit.

page 24 has a 2015 jeep hack.. you think 2022 jeep has less connectivity?

Pretty young, eh?

Then what's this?
It's even not that far off from Hydro blue metallic........... There wasn't even a brick phone when these were made in the mid 1960s.
I bet if you mentioned "canbus" to them they'd say, oh, the bus to Canada.........

That's why I suggested a signal jammer. You can leave everything connected, turn it off if necessary or when at a dealership...... They are not legal in the U.S. but I suspect it wouldn't be hard to make something that would be very limited in scope - block only the truck's functions.
Or again - the tazer people may have some insight.

It's been said that Russia has the capability to cause widespread EF issues taking out power grids, and stopping vehicles - but in that case even your grandpappy's 49 Ford would be dead, then. We live in an age where even if you shut off the new technology, the old will be impacted just as easily by the right foe.

@ShadowsPapa Jammer are off the table, to high a legal risk with hefty fines and jail time, plus the personal liability if you block the cars cell signal next to you and they are calling 911 for a medical emergency. I would strongly suggest please don't encourage ppl to do this.

Don’t be so sure. It’s very possible that a disconnected LTE antenna could throw a code. Dealers need less ammo than that to not honor an electronics warranty. All they need to say is, “the owner disconnected parts that aren’t customer serviceable”. Then you’d need to prove that your modification didn’t affect something else. Even if it didn’t, you’re fighting an uphill battle.

 

[Dougstdig]

Yes.
You can use the UConnect App for remote starts.

Kevin

Only if you have remote start…

 

[NachoRuby]

Only if you have remote start…

Or a radio that is compatible with the uconnect app.

I have the radio…but was told I couldn’t even add it.

 

[ShadowsPapa]

........ well, isn't that sort of a DUH?
Can't do remote start if you don't have remote start..........

Jeep would really lose if you could do a remote start simply by using the app even if you didn't pay for the remote start capability.

Or simply reattach it and bring it in. No proof that anything happened. Either way, considering how many here add lift kits and other items like that, this is a relatively low risk thing to do. Just reattach the antenna.

But I fully expect my lift and gear upgrades to void my axle and suspension warranties. Oh well I guess.

The problem with disconnecting the antenna is that it can possibly burn out the transceiver by attempting to transmit with no antenna attached. Of course, if that's your goal, you wouldn't be trying to get it repaired under warranty.

Very possible.
