Removed from my 2017 Mini F57 as the antenna connection wasn’t working with the snap-in adaptor.

The issue was that the antenna cable had been installed under the metal base so the cable was broken!

You can see the antenna plug on its own.

Most people would now remove the snap-in adaptor and replace with the wireless charging shelf/cradle (BMW part # 84102449887) which comes with its own antenna cable so this one would be removed.
