When i have my map on (either Waze or google maps) and my location switched on and driving in my car, once i reach over 100km/ hr there is an annoying beep that occurs, either over the phone or bluetooth speaker. (One beer per second). If i go back under 100 km/hr the beep stops! It doesnt matter what speed zone I'm in.
If i switch off my location the beep stops, which means my maps wont work!!
