parking sensors volume

[Gabz]

is there a way to increase the volume of the parking sensor on a GL (x166) MY13?
the rear ones are hardly audible while the front one are marginally better
than you

Did you get an answer to this? I also struggle to hear the Audible beep, especially with kids in the back.

Does it have parktronic? It might be that you're meant to rely on the visual indicators. Where does the sound come from, does it have a dedicated speaker? Maybe it's obstructed and can be re-positioned.
