5. Operation Modes and Compatibility

The device supports two primary operation modes:

• OBD Mode: This mode reads data directly from your vehicle's On-Board Diagnostics (OBD-II) system. It is generally compatible with most car models manufactured after 2008.
• GPS Mode: This mode uses satellite signals to obtain driving data. It is compatible with all vehicles, regardless of make or model year.

The device will automatically attempt to connect via OBD first. If OBD data is not detected or if your vehicle is not compatible, it will switch to GPS mode. You can also manually select the preferred mode through the device settings.
