    Read the safety guide

Before the first drive

  • The device and harness are fully seated and the mount does not block your view.
  • The screen identifies the expected car and does not remain in dashcam mode.
  • You understand the alerts and stay ready to steer, brake, or accelerate at all times.

Something went wrong?

If the device stays in dashcam mode, recheck the exact car configuration before changing software. For hardware problems, return to stock before contacting comma support.
