3. ROUTE GUIDANCE VOICE GUIDANCE The voice guidance provides various messages as you approach an intersection, or other points where maneuvering the vehicle is necessary. CAUTION ● Be sure to obey the traffic regulations and keep the road condition in mind especially when you are driving on IPD roads. The route guidance may not have the updated information such as the direction of a one way street. 2 APPLICATION-"Map" When is touched while route guidance is active, the last navigation announcement will be repeated. After touching , touch "+" or "-" to adjust the volume level of the navigation announcements. After touching "+" or "-", short audible information will be given to control the current volume level (e.g. turn up/turn down). INFORMATION ● The street names may not be pronounced correctly or clearly due to the text to-speech function. ● On freeways, interstates or other highways with higher speed limits, the voice guidance will be made at earlier points than on city streets in order to allow time to maneuver the vehicle. ● If the system cannot determine the current vehicle position correctly (in cases of poor GPS signal reception), the voice guidance may be early or delayed. 45
