Looking for some advice on how to remove the shark fin from my 2017 xf or how to get access to the antenna from the headliner side.

thanks

 

If you need to remove the antenna, you have to drop the headliner, at least the rear portion. There is nothing fun about it. The rear clip is also one time use cause they normally break during removal. After that, everything is easy. YOu replacing cover or complete antenna?
