How to turn off speed limit warnings?

[V1nny]

I picked up our new Motorhome a few days ago. The problem is, it keeps giving me loud audio warnings that the speed limit is 48kmh, or 62kmh or 82kmh, etc. It is driving us mad and most of the time the limits are wrong. Does anyone know how to turn this function off? I have looked through the various handbooks and can’t find anything.

The vehicle is a 2017 Burstner Ixeo Time Sovereign 734, on a 2.3L Fiat Ducato, with a Pioneer AVH-X5800DAB audio system.

Thanks
