Review on ACDelco 23258394 Original Equipment Frequency by Rubeen Black

I bought this after I started having a small leak under the visor. My 2014 has both navigation and XM radio. I was out of warranty and didn't really want to go to the dealer to claim my extended warranty. I've heard people have nightmares without their truck for a week and pay over $400. Pretty easy and can be done with basic tools. You need to remove the A-pillar from the dash and driver's door, lower the handle and remove the visor (think T10 driver's head). The headliner is flexible enough that you bend it slightly and get a 1/4" ratchet with an 11mm socket on the single nut holding it. The connector can be disengaged by inserting a small, straight screwdriver of appropriate length into the top. red connector above. Lift the tab slightly and pull the wire. Since this GM design still has a slit on the back, I highly recommend using a strip of clear silicone around the bottom. Tighten until the expansion sleeve on the bolt engages the roof.
