Micro SD Cards play an important role in dashcams, but not all cards are suitable for dashcams.

We recommend UHS-I U1/U3 rating, high or max endurance microSD card.

The max size it supports is 256GB, 128GB card will be preferable. Please refer to below when choosing a card.

Please check if there is a power supply issue, if you use a 3rd party charger, we highly recommend trying the original car charger and adapter.

Please test both the GPS mount port and camera side port.

It’s normal the dashcam becomes hot during recording, especially for A129 PRO 4K. 

There is a High-temperature protection mechanism inside, the camera adopts heat discharge construction and the built-in sensor can detect the temperature of the main chipset. When the inside temperature reaches a certain degree, the device will automatically shut down to protect itself from overheating.

We do not suggest you expose the camera to high temperature for too long.

There are GPS mount and non-GPS mount, if you have bought the GPS mount, you may check by the right side of the camera screen. There are 4 situations you may encounter. ① Green speed and satellite icon: GPS enabled and working, which is totally normal. 

② Red speed and white satellite icon: GPS enabled and searching for signals, it generally happens when you are in the parking lot or somewhere with a poor satellite signal. 

③ "NO GPS" icon and satellite icon missing: GPS not detected. if you have actually installed a GPS mount, you may need a new GPS mount. 

④ Null: GPS disabled.

We suggest using basic functions when troubleshooting the issue. 

① Please use the original car charge cable, disconnect the rear cam, disable WiFi and parking mode to try.

② If the issue continues, please format the card, try a recommended card.

③ If issue persists, please update the firmware and reset the camera

First, please make sure the hardwire kit is connected correctly, use a multimeter to test the voltage.

Choose the highest protection cutoff voltage 12.4V/24.8V. 

You can power by either port, there is not much difference, you can choose the one better for the wiring on your car.

The standard length of the rear cable for the dashcam is 6M, and it can not be extended manually.

There is an 8M longer one you can purchase

It can only support 4K 30fps and 2K 60fps at present.

You can reset the password to the default number 12345678 by updating the firmware.

It is the yellow ACC cable that detects the voltage change and switches the camera between parking mode and the driving mode.

So please recheck the hardwire kit and fuse tap connection. Reset the camera and choose low bitrate parking mode to test again.

You can refer to the following YouTube videos to check if you installed the hardwire kit correctly.
