C205 A piller

[rom1]

Looking for some help on removing A pillar on cabriolet 2017, it is not like the saloon version at the top it wraps around and the sun visor sits on that part
I'm adding an external USB Dab + aerial and it needs to earth to A pillar so I can squeeze the wire in from the wheatear strip like you do for dashcam.

TIA

Its clipped in so you just need to pull it towards you firmly. Its very easy to break the plastic clips.
