I had that on a car I owned and although I would prefer it to be a MILF detector it was not.
That is an aftermarket parking sensor indicator. The L and R letters on the 2 sides show the side on which the parking sensor is detecting something and a series of bars starting from the centre towards the L or R show how close you are getting to the obstacle. The square box in the centre of the screen with the m letter shows approximate distance in metres (starting from 1.5 if I remember well) from the obstacle.
