Elite VRVD640G Off-route Sensitivity, Recalculation Delay, Turn Penalty, Cross-Border Planning

Navigation System

vice, the GPS antenna location in the car and the environment you are driving in, route recalculation can behave differently. Cydle may think you have departed the proposed route and perform a recalcula- tion even if you have not done so.

When the GPS reception is poor (e.g. driv- ing in an urban environment with a low sen- sitivity GPS), occasional wandering (called position fluctuation) of the calculated GPS position is likely. Although Cydle employs

asophisticated Lock-on-Road system that will mostly suppress these position errors by aligning your position to the recom- mended 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 Cydle how far the GPS position should be from the recommended route before the program decides to recalculate. Lower values make Cydle 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.

U-Turn Penalty

You can fine-tune the way Cydle takes U- turns into account when planning a route. You can tell Cydle 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 Param- eters.

Cross-Border Planning

By default Cydle 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.

Keep Position On Road (Lock-on-road) Cydle is normally used for vehicle naviga- tion, therefore Lock-on-Road 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 Cydle 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.

USER DATA MANAGEMENT

Everything that was saved (pins, My POIs, Favourites, track logs etc.) or modified (Settings, History lists) since Cydle was in- stalled is stored in a user database located in the internal memory of the PNA. Here you have options to save, restore or reset the database or parts of it.
