Understanding the speed indicator
The speed value displays in red when the vehicle exceeds a speed threshold. This provides a visual alert so you can quickly identify vehicles that may be speeding.
Device health alerts
If a vehicle has a device health issue, the vehicle balloon on the map displays a Device health card with a status indicator (for example, "Critical"). Each issue includes a Troubleshoot link that directs you to steps for resolving the problem.
Common device health issues include:
- False towing detection.
- Incomplete installation.
