6 "bongs" whilst driving (no warning light)

[Oreo22]

Following a recent update on the satnav mine does this when entering an average speed camera area and the speed limit sign come on satnav screen with a camera cut through the bottom of the speed sign. Six bongs and when you leave 2 bongs of a different tone.
I have been learning how to turn some of them off as they are distracting and unnecessary.

I wish mine only bongs 6 times for no apparent reason!
