Default How to remove ONSTAR antenna? 2017+ models

I have a base 2017 Stingray and have located the ONSTAR unit and it has what appears to be 2 antennas. Which to remove - I have heard the brown one. I cannot figure how to unplug them - it is different attachment than the older models. Can anyone tell me which one or both to remove and how to unplug them? I am trying to avoid the check engine light and the other features being disabled. Thanks all!

What does the OnStar antenna have to do with the Check Engine light? Even fully functional with an OnStar Account the system has no ability to set a check engine light. If it fails there is a code set in the VCIM module but you wouldn't know about it unless you hooked up a scanner that could read body codes.

Still looking for the answer if anybody knows. Which antenna to remove on the 2017 and what to do to make it come loose without damage - it does not appear to twist off, push off, pry off, etc...

Why are you trying to disconnect the antenna at all?

I think the antenna connector can be removed after you open (or remove) the red plastic retainer clip.

Below is a thread (See the first post of it...) that shows how to easily remove the cellular radio module that is inside OnStar box. That is a better solution than just disconnecting the antenna, as some RF signal can still be emitted by the open coax cable, and could be picked-up if you are very close to a cell tower. The OnStar box is on the passenger side, behind the plastic trim panel below the glove-box.

Thanks - I saw this post before I went into it and it helped a bunch. I found the box under the carpet behind the glove box but the connectors on the 2017 are different. There are 2 antennas but I want to retain the functionality of the bluetooth microphone and not risk breaking/losing anything in case I sell it later. As far as the reason for this - Call me silly but I just want it GONE.

Worries about OnStar tracking his car's movements.

Wants to retain connectivity to a smartphone that tracks his movements.

Why not just pull the fuse for the OnStar crap?

You can remove the Onstar module fuse # 27 (under the rear cargo floor), but you will also lose the Blue-tooth feature (Same module does both).

As has already been said - pulling the fuse kills bluetooth microphone. Pulling the antenna does not. I can get to the module and see the antennas but they have a different design from prior years and I cannot get them loose and I would not know which one or both to remove.

Why not just wrap them in aluminum foil? That should suppress the signal.

One should be for LTE/WIFI and the other is for Bluetooth. You have to disconnect both, crack open the box and pull the LTE/WIFI card if you really want it dead. I looked online seems like the connections are the same as my post.

What is the purpose of disabling OnStar?

Where is the antenna(s), and how do we get to them?

Some people don't believe wrapping their head in aluminum foil is sufficient to stop the spying. The best argument against OnStar tracking anybody is none of us are that important to be tracked if we haven't paid the money to be tracked. Even then it really doesn't track you.
