## Questions & Answers

**Q: Does the mirror dashcam only record front camera video?**
A: G840S saves front and rear videos. Click the [playback icon] to enter the playback interface. Then Click the [car-shaped icon] to switch the video interface of the front and rear cameras.

**Q: Why the rear camera glares at night?**

**Q: Rear Camera not detected?**
A: First, please check the AV connector and 4-pin connector (4-pin connector may be loose, you can tighten it and reconnect it) and reconnect the AV connector to check whether the rearview camera can be detected. If still doesn't work, please tell us.

**Q: How to filp/mirror the rear camera image?**
A: If you want to install the rear camera on a pickup, SUV, or even on the top roof more conveniently, please adjust the "Upside Down of Rear Camera" and "Mirror Flip of Rear Image" menus to adjust the rear image vertically or horizontally.

**Q: Why is GPS not working?**
A: The vehicle must be within a wide range to receive the signal. We will send a new one if it is still not received in a wide area.
