There is a small box about 1.5 inches square behind the mirror. It’s bigger than a motorway pass and more robust.

Picture below .... who knows?

My L405 has a camera in there - we are being watched and monitored by LR! 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

RR can watch what they like...as long as they don’t tell the wife!

I just thought this might be a gate opener or similar and would then want to track down the make.... to utilise same.


Bill Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits. Emissions Analytics worked with........etc etc

There's the rain sensor in there for the windscreen - I think also some sort of light sensor for high beam assist & maybe other things too.

If you have the the HomeLink option - that will do gates - it will be buttons on the under side of the mirror
