Interior A pillar trim removal for Dab aerial

[GazzaM100]

How is the passenger interior A pillar trim held in place?
Also is there anything behind it to actually ground a windscreen Dab aerial to?
Similar to the picture
Cheers

Looking at the pictures from my interior re-trim, the A pillar trim is glued in place and the windscreen is bonded on top of it all. Underneath is a steel hoop that would provide an earth but it is buried under a lot of padding.
Best left alone.....

Have you tried it? My one in the Griff works great without the earth.

Cheers for the replies anymore suggestions welcome.

I haven't tried it yet as not got access to the car at the moment but want to do it all in one go while the lower dash is out, as in fit new stereo, aerial and reverse camera.

Have you got a picture of yours fitted in the Griff by any chance?

If you mean the aerial? Difficult. Fitted unit and tried the dab and it worked so I just stuck it on the underside of the dash top above the glovebox. (Excellent signal as well.)

Cheers, suppose its best to have a play before it's put back together

The hoop is on the other side of the windscreen adhesive and quite a way around the corner from where the antenna is mounted. In any case, I don't think it'll be a good ground.

I've known many of these antennae to work fairly well without being ground but my understanding of them is that they perform much better when they are.
