My HUD works great, sunny or rainy. You can adjust the brightness.
I am in the US and my HUD does recognize stop signs and changes if it sees a different speed limit sign.
I drive to work 30 miles on Interstate 95, speed limit 70 MPH.
As I enter I-95, 70 MPH shows up on my HUD. Over the last few years my section of I-95 has been expanded.
Part of the expansion created a full lane for the right side shoulder, great if you have to move off the road.
For these shoulders the State has added a speed limit of 40 MPH if on the shoulder.
I generally drive in the middle lane but if I drive in the right lane and pass one of the 40 MPH signs, my HUD will change to 40.
I have to drive by another 70 sign and it will change back to 70.
They say that the US cars do not recognize signs but mine does.
