Shark fin
Was easy to install, only needed a few tools and with the help of YouTube video it was simple.

Fixed my Onstar red light status!
This worked perfectly to replace the Onstar antenna on a 2014 Silverado.My Onstar had been giving me the red light status and a remote diagnostic identified a communication issue with the antenna. I ordered this and watched a video online on how to install it.It was a perfect fit and the install went smoothly.Once reconnected the status light went from red to green and another remote diagnostic reported everything was ok. Success!

Perfect fit and fuction

fixed the problem
this item saved me a ton of money. We thought the temp control was bad but this fixed the problem. Would recommend that you change the cabin filter at the same time.

excellent price, it is equal to the original
It is exactly the same as the original, it only took about 20 minutes to install and the nav recognized it immediately, the most difficult thing is to remove the roof.

Fixed my navigation with red x through gps
2015 suburban had a red x through the gps on the navigation screen and was showing my car in middle of the ocean. This fixed the problem and took only about 15 minutes to install. It was a little hard to get to in a very tight spot above the head liner, but it plugged right in and the navigation reset itself.

Perfect fit
Ordered this for my 2014 GMC sierra. Old shark fin shorted out. Installed this one and worked like magic. Didn’t have to call Sirius XM or anything. Just turned on the radio and boom it works. Quite happy with it. I suggest you remove your old one and get a number off it for reference because there’s tons out there
