PX2 Tyre sensor antenna location?

I'm wondering if someone would know exactly where the antenna for the tyre sensors is located in my PX2 XLT with Tech Pack? Is it above the roof lining or behind the black plastic bit near the camera on the windscreen?

I run a clip on rear view screen on the existing mirror which interferes with the tyre sensor signal causing an alarm on the dash quite frequently. I know it's the screen as with it turned off there's no problem. I've also wrapped the rear of the screen in alfoil which has dramatically reduced the error, but not eliminated it.

If I know exactly where the antenna is, maybe I can shield it or even shift it away from the screen a bit?

Any intel will be appreciated. :)

I should add that I have several ferrite sleeves on the cable already with zero improvement.

The info in the manual I have shows only the BCM and the wheel sensors as components in the system and only mentions those two parts for training etc.

Yep, TPMS receiver is in the BCM.

Ok, that makes sense, but I'm sure I read somewhere that there's a receiving antenna up near the roof somewhere, perhaps connected to the BCM to provide the signal?

TPMS receiver is above and to the the drivers side of the map lights/glasses holder in the headlining.

Module sends received data over LIN and MSCAN to BCM.
