Additional information ENGLISH How you are guided • If GPS signal reception is poor, navigation guidance may not be correct. • The System may not receive GPS signals in the following places... - in a tunnel or parking lot in a building - under an overhead road - in a place surrounded by high buildings or by closely standing trees • Make sure to connect reverse signal lead (☞ Installation/Connection Manual); otherwise, your current position may not be displayed correctly. • The position of your car may not be detected correctly in the following cases... - when driving on a road close to the other one (e.g. a highway and ordinary road running in parallel) - when turning at an almost straight fork in the road - when driving on a gridiron road - after taking a ferry, etc. - when driving on a steep mountain road - when driving on a spiral road - when turning left or right after running on a long straight road - when driving in a zigzag line on a broad road - when starting your car shortly after starting the engine - when driving for the first time after installing the unit - when changing tires or attaching chains on the tires - when tire slip occurs continuously and frequently - after driving on areas other than a road (e.g. private lands or parking lots) - after driving in underground or tower type parking lots - after rotating your car on a turntable - after frequent stops and starts in a congestion - when the accuracy of GPS is deteriorated intentionally - when driving on a road constructed recently • The route calculated by the System is one of the possible routes to your destination. The route is not always the most appropriate one. • If no-exit roads (only entering the rotary from the roads is allowed) exist on the rotary, the no-exit roads can neither be shown in the route guidance on the display nor counted in the route guidance voice message. • The following phenomena may occur even if the System is working correctly... - It may guide to a closed road or to a route requiring a U-turn. - It may not guide to your destination if there is only a narrow road or no road to your destination. - It may show a different road name. - It may not ask you to turn at a junction even if you need to. - It may give guidance different from the actual road conditions. - It may give incorrect distance information. 41
