In device-assisted navigation, audio navigation cues are often presented at particular locations along a route (e.g., “in 200 meters, turn left” and “turn left here”). However, if the user stops, navigation cues also stop since the user's position is not changing. Additionally, the navigation instruction at the next navigation point may be conflated with the actual position of the next navigation point; e.g., an instruction to “turn left” may be confusing if the road takes a sharp right turn immediately before the next navigation point. Instead, the device may periodically compare the current position of the user and the next navigation point, and periodically present guidance audio cues that indicate the distance and heading offset to the next navigation point. Guidance audio cues may be integrated with and/or supplemented by audio navigation instructions to indicate both the location of the next navigation point and instructions to be followed there.
