Adding XM antenna to avoid camper overhang
I thought that I would share an easy way to add an XM/Sirius radio antenna to a 2019 GMC 3500 that is not blocked by an overhanging cab over camper. For my application I need two parts. 1 XM Satell...

Got this done today with generic parts that were less than half of the factory parts listed in that bulletin I posted.
I ordered a generic magnetic mount puck antenna with this adapter.
My truck has the navigation system with the sharkfin antenna at the front of the roof. First step is to remove the passenger A pillar trim. Pop off the two fastener covers and there is a 10mm bolt behind each.
Lower down on the A pillar you'll see this connector:
There are 2 wires: the thicker one handles nav and 3G data service, the thinner one is the Sirius/XM antenna.
Detach the connector from its mounting clip then depress the tab to open the connector
There is a yellow clip that holds both connectors in the plastic clip. Pop that out and the connectors will come out of the clip...DON'T lost that yellow insert! Pay attention to what side of the connector the small-wire satellite radio antenna goes in. With this particular connector, I had to drill out that side to 15/64" to get the connector to fit.
On the adapter, there is a blue clip that pops out, and once out will let the antenna connector come out of the clip. What we're going to do is insert that adapter connector into the factory clip in place of the factory antenna connector.
I ran the new antenna wire behind the door weatherstripping and placed the magnetic antenna on the fender.
Works great! Hop it works as good with the camper on!
