I now have an Inforad V3 GPS-based "detector". Still apparently illegal here but I'd argue my corner (by hiding the little UFO when necessary ).

And yes, the fairly-new camera up the road from me was detected. It also works through my headed windscreen....so I'm happy (fixed cameras not mobile installations are in its database - better than nothing and thus very good for reminding me to not speed when I am somewhere new looking for where I am going)
