DampDuffer is right. Welcome to the confusing world of Toyotaland electronics - the HUD speed limit display is fed only by speed limit signs that the car can "see". No speed limit signs, no speed limit shown in the HUD. You would think that since the vehicle's GPS knows (almost all the time) what the speed limit is it would be shown in the HUD and, if speed limit signs showed a different limit it would override the limit in the GPS but, alas no, that would make too much sense. As I said, welcome to Toyotaland...........
On a related note, I have noticed that dynamic nav (2020+ RX) doesnt correct this in GPS when a speed limit on a particular street has changed in the past few years. So in those instances, two different speed limits show, the one picked up by the RSA camera and the one from the GPS data (whether stored in the vehicle or downloaded from the cloud). I dont know anything about the dynamic nav, but assumed it would load updated streets and other data but my expectations were clearly too high. Im sure it also depends on how recently the GPS data provider refreshes their data, but there is a three year old change in my area that still has the old speed in GPS. I didnt think it would take so long for the GPS provider to update (and yes I know this may not be the same issue for phone based GPS)
