Abstract
The invention relates to a method and a device for combining an in-vehicle navigation system with a sound system in a vehicle. The combination permits the navigation system to project audible maneuver instructions to a driver. While projecting the audible maneuver instruction to the driver the vehicle navigation system moves the location of the projection of the maneuver instruction from a first location to a second location. The first location does not coincide with the content of the maneuver instruction and the second location does coincide with the content of the maneuver instruction. Thus, a system is provided wherein the driver perceives the audible maneuver instruction as moving in a direction which coincides with the content of the instruction.
