2014 XM Module Location

Toolbox1 · May 23, 2017

Looking for the xm module location on my 2014 LTZ. Specifically where the xm antenna plugs into the module. I have a external sirus head unit that I paid for a lifetime subscriptions years ago. I would like to use the external unit and leverage the stock antenna. There are a ton of videos on how to do this but all show a 2013 which has the module behind the glove box. Is that where the module is for the 2014?

I should mention I have the 8 inch my link screen with xm installed. Just would like to use my xm head unit with the aux.

Thanks!

Directly behind the screen. AM/FM/XM radio and Onstar radio's both behind the screen.

Excellent! Thanks. Will look for a wiring diagram to determine which wire is which.

The coax with the yellow end is for XM

For your 2014 LTZ with the 8-inch MyLink screen and XM installed, the XM module location might vary slightly from the 2013 models. Typically, in 2014 models, the XM module is still located in the passenger side area, but instead of being directly behind the glove box, it might be under the dash or near the A-pillar. However, it's not uncommon for there to be slight variations in module placement even within the same model year, depending on the specific features of the vehicle. To leverage the stock antenna for your external Sirius head unit, you'll likely need to access this module. If you're unable to locate it based on these guidelines, consulting the vehicle's service manual or a professional installer might be your best bet for a precise location and advice on making the connection.
