Conditions likely to cause noticeable positioning errors

Certain conditions are more likely to cause discrepancies between your actual position and the location
shown on the map display.
• If you make a slight turn.
• If there is a parallel road.
• If there is another road very nearby, for example, an elevated motorway.
• If you take a recently opened road that is not on the map.
• If you drive in zig-zags.
• If the road has connected hairpin bends.
• If there is a loop or similar road configuration.
• If you take a ferry.
• If you are driving on a long, straight road or a gently curving road.
• If you are on a steep mountain road with many height changes.
• If you enter or exit a multi-storey car park or similar with a spiral layout.
• If your vehicle is turned on a turntable or similar.
• If your vehicle's wheels spin, such as on a rough track or in snow.
• If you put on chains, or change your tyres for some of a different size.
• If trees or other obstacles block the GPS signals for a considerable period.
• If you drive very slowly, or in a start-and-stop manner, as in a traffic jam.
• If you join the road after driving around a large car park.
• When you go round a roundabout.
• When starting driving immediately after starting the engine.
• If you insert the disc and turn your Navigation System on while driving.
Some types of vehicle may not output a speed signal while driving at just a few kilometres per hour. In
such a case, the current location of your vehicle may not be displayed correctly while in a traffic jam or
in a car park.
