GM Genuine Parts 84346784 High Frequency Antenna

Watched a few Youtube videos to get an idea how to attack this. Learned that due to the added features there were more wire harnesses in the head liner making removal of the head liner less of an option. Was able to get up inside to get the bracket on the back side clipped. Due to the damage to the area around the mounting hole I had to do a little body work first. As soon as I got everything aligned and straight the new antenna sat flush to the cab. While doing the install I did apply dielectric grease around the ground connections and sealed the outer edge with silicon. Never had any calibration or other issues either. Works like new. Looks perfect.

My Escalade lost GPS capabilities and this was the fix. I painted it with the color code and cleared it also. The process to install was on YouTube and it took me about 45 mins. Probably saved $500 or more versus going to a dealer. Thanks for a gray product at a great price!

This is a genuine GM product and came with holographic labels to prove it. The OnStar button on my 17 gmc sierra was red instead of green, and things like gps, the app based controls (autostart), etc weren’t working. Dealer quoted around $600. This cost me about $75, an hour of time, and a beer. There are several good videos on YouTube how to do it. This fixed all of my connectivity problems! The OnStar light is green and all of those features work great now. Truely a great deal.

Took care of my problem it did the job

Perfect replacement worked perfectly for Chevy Silverado. Fixed the no signal for gps and satellite radio.

Reasonably priced, I now have a working GPS in my 2015 Silverado!

The description does not specify witch vehicles this part fits. Do yourself a favor and take the old one out first and read the part number. These are not all the same even tho they all fit in the hole.. After replacing the failed unit with this part XMS radio will not work. NAV and OnStar works but no radio. I had to order the correct part but it was OEM and the weep hole is still on wrong end. I liked this model because it was a GM upgrade and the weep hole was on the down slope to allow moisture to escape. The original had the weep hole at the top allowing it to fill with water and eventually fail.

Direct swap to my original GPS antenna. This fixed my GPS and navigation system. Direct plug in and no wires or electrical modifications.
