Garmin Edge 1040 Direction Checklist sound

Hello,

Since the last update my Garmin devices makes noises like a tamagotchi.

When I load a route for navigation a alarm is going like 20m before I habe to take a turn. Then once again like 5m before. That's fine and I love it. It's the double "beep" coming out of the device. But since the update, it make a single "beep" after I passed a turn and it's showing up on the display. This is fucking annoying since I'm mostly riding gravel routes with a lot of commands. So is there any way to turn of this annoying "new feature"? Please... I need the noises for navigation but this additional one drives me crazy!
