Symptoms
- Poor GPS reception
- Straight Lines on the Map
- Vehicle going over Buildings, trees, etc.
- GPS coordinates do not change under View Accident & Log Data
- Vehicle location is not accurate on the map
Cause
GPS performance may be compromised due to:
- Poor weather conditions, such as dense clouds or heavy precipitation
- The receiver is in an environment where physical obstructions, such as mountains, deep valleys, tall buildings, overhangs, bridges or tunnels are apparent
- The receiver is obstructed by something within the vehicle
- The device is not properly installed
- The use of a three-wire harness with different ignition detection logic; you can find appropriate harness using this guide
- The use of GPS jamming equipment
Workaround
Resolution
- Ensure proper device installation and location for better GPS reception. This will not guarantee GPS latch if issues are due to external environmental factors however.
- Three-wire harness installation may result in straight lines on the map at the start of a trip before ignition is detected.
