Anyone have a link to how to get the door panel off?

Thanks, JimCost2014: Not sure what radios the antenna in the shark fin serves, but my AM/FM radio is working just fine. Do you know if that means anything about the shark fin and the XM not working? BTW, thanks to YouTube, I opened up the radio compartment and checked all cable connections. no problems there. While doing this, I discovered that the XM module in my 2014 Sierra is located behind the screen and above the AM/FM radio, NOT next to the glove compartment as claimed by several YT videos.

1 fast ss: How did you resolve your issue? I have the same problem with my 2014 Sierra. XM worked fine for 6 years. In the last few weeks, I have been getting "No XM Signal Reception may be blocked". However, the raadio does work occasionally for 3-5 minutes, so I wonder if it is just a loose antenna cable. The AM/FM radios work fine.
