1. The following cases are not system failures
Situations that may affect position determination:
- Sometimes, when driving on the highway/viaducts, the floating point fluctuates.
- When you are driving on a very steep road.
- When moving along a serpentine, you can find that the floating point oscillates. It has nothing to do with the radius of the road and the speed of your vehicle. One reason may be that the actual road conditions may differ from the electronic map information.
- When turning right/left onto a road with parallel roads nearby (at a distance of less than 50 m), you may find that the floating point may move to a different road.
- When driving on a wide road with a lane change, you may find that the floating point oscillates due to the inconsistency with the actual distance.
- Before exiting the underground parking, if you have been driving underground for a while or in a multi-level parking spiral, you can find that the floating point is swinging. When your machine is on a rotating lift, the floating dot arrow may point in the wrong direction.
- Voice prompt at the adjacent road ahead.
- The reported distance may differ from the actual distance.
If any of the following situations occur, the GPS satellite will automatically adjust the location fix if you keep moving.
Issues related to map files:
- When driving from a newly constructed road to a road that is recorded in a map file, you may find that the floating point is unstable because the actual state of the road cannot be displayed in the map file. If you keep driving for some time, the system will automatically adjust the required position using the GPS signal.
- Passage is not possible due to a marked cul-de-sac or pedestrian zone
- Opening a new road or closing an old road;
- Direction to the road with a closed passage;
- The route is recalculated without changing the proposed route;
- Direction to a normal road instead of a viaduct or vice versa;
- If there are several small lanes near your destination without a normal road, the system will only guide you to a place near your destination.
- An instruction to make a 180 degree turn;
- There is no sign next to the adjacent road;
- Turn instructions do not correspond to real road conditions;
- There is no direction indication or entry/exit voice guidance when escorted on a highway or expressway.
- The schematic map may not match actual road conditions.
Locations where GPS satellite signal reception may be difficult:
- in the tunnels;
- Between tall buildings;
- Under viaducts;
- In forests;
When using an external GPS antenna, we recommend placing it on the roof of the car. If your vehicle has an optional roof rack, do not connect the antenna to it.
GPS is operated by the US Department of Defense. The accuracy of the signal can be forcibly lowered, which leads to a chaotic movement of the symbol of your car on the map.
Usage Notes:
- The floating point may oscillate before receiving a GPS signal when the power is turned on.
- The floating point may fluctuate when using the system for the first time after installation.
- The system will automatically adjust its position and heading using GPS signals when the position of the floating point does not match the actual conditions.
