position to the recommended route and the road network of the map, sometimes the errors are too large to correct. To reduce the effect of large errors, you can increase the recalculation tolerance two ways. Off-route sensitivity This is a range of relative values from 0 to 10, telling The NVX225 Navigator how far the GPS position should be from the recommended route before the program decides to recalculate. Lower values make The NVX225 Navigator insensitive to position errors; higher values will result in quicker reactions. Recalculation delay This is a setting that helps suppress the effects of position fluctuation. With a few seconds delay in recalculation even large position jumps can be survived without a need for route recalculation. 5.6.4.2 U-turn penalty You can fine-tune the way The NVX225 Navigator takes u-turns into account when planning a route. You can tell The NVX225 Navigator how much extra distance you would travel to avoid a u-turn. Note: This value is taken into account only if U-turns are enabled in Route parameters (5.4.4.4). 5.6.4.3 Cross-border planning By default The NVX225 Navigator plans routes using the border crossing points. However, if you live near the border, you can disable border crossing with this switch to remain within one country. 5.6.4.4 Keep position on road (Lock-on-Road) The NVX225 Navigator is normally used for vehicle navigation, therefore Lock-onRoad will display the position arrow precisely over roads, seamlessly correcting small GPS errors. For pedestrian use you may consider disabling Lock-on-Road to make The NVX225 Navigator always show your exact position. Note: By turning off Lock-on-Road you also turn off the GPS position error filtering. The position shown on the map will be subject to all position errors and position fluctuations. 72
