Garbage quality and poor software.
GPS fails, touchscreen becomes unresponsive, software is unintuitive and slow which combined with the poor touchscreen makes using it an exercise in futility. Dashcam only records in 1080p 30fps instead of 60 like even the cheapest dashcams from ebay. 499 is an absolute ripoff for this device, you will spend less money on getting both a purpose built dashcam and separate GPS from a company that knows what they're doing like Tomtom. I've had budget phones from over 5 years ago that perform a better job with GPS navigation. Avoid like the plague.
