This is my first post so please be kind. I've read lots of threads but ended up more confused than before. My problem is when i use speedcam test all speedcams say ( speed limit 50kph ), which i thought was just a test issue but when i navigate and come upto a camera no matter what type it is i get the same notification ( speed limit 50kph ) ,can anyone help me , i'm 68yrs old so no spring chicken , but not a dummy.
