This is a custom car cell phone holder mount designed specifically to replace the dashboard panel cap on a 2019, 2020, and 2021 Chevy Silverado and GMC Sierra 1500 2500 3500. It will fit some later models like the WT versions. If the dashboard looks exactly the same as the pictures, it should fit.
 
For those models that did not come with a trailer brake controller, which leaves the bottom left panel cap on the dashboard, this dashboard phone mount will "smash and twist" right into that spot and put the ball that your cell phone holder grabs on too in the perfect spot. The only area that doesn't cover any buttons or line of sight. 
 
NOTE: The Driver side and Passenger side holes are not the same. They are not interchangeable.
 
You may already have other mounts that hold on with suction cups and come up from the bottom, but it always comes loose after a while, and is pretty worthless while off-roading. This one utilizes that wasted space on the dashboard and gives you the most sturdy and attractive phone mount available for the Chevy Silverado and GMC Sierra trucks.
 
The panel cap itself needs to be taken off and is easily released from the inside. You'll have to access that by carefully popping off the rectangular accessories panel to the right of it with the included FREE plastic panel tool.
     *If you DO have the trailer brake controller, it is not recommended that you try to take that out unless you know what you're doing.
