Review: Exact replacement for the "Shark Finn" 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.
Review: Excellent product, fit 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!

### ⭐⭐⭐⭐⭐ Exact replacement for the "Shark Finn" antenna
*by J***M on January 26, 2023*

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.

### ⭐⭐⭐⭐⭐ Excellent product, fit perfect.
*by J***W on June 21, 2023*

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!

### ⭐⭐⭐⭐⭐ Fixed OnStar red light
*by R***S on December 4, 2025*

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.
