Why doesn't Regal reverse radar display the distance?

Not all reversing radars will show the distance. The models of reversing radar produced by different manufacturers are different, even the reversing radar produced by the same manufacturer will be different.

At present, the mainstream reversing radar mainly includes digital display distance, sound prompt distance (the closer the distance is, the more urgent the sound is), and display obstacle position and distance (indicating that the obstacle is on the left or right side of the vehicle).
