I configure some POIs with a sound alert (for example, a sound is played when I am 500m near a gas station). It works fine.

My problem is I lose those settings when I update the map on my TomTom Go 740.
How can I save my POIs settings ?

I have my POI on my disk, the problem is the lost of my warning's settings.

I was told to Copy the "mapsettings.cfg" from the old map folder to the new.
It works, I do have my favorites and my recent destinations. I add my POIs but I haven't my warning's sounds, I have to set them every time I update the map :/

Thank you for the help !
