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 the 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, as well as other power supplies.

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

There is a High-temperature protection mechanism inside, so camera shall turn off and restart when it overheats.

We do not suggest you expose the camera to high temperature for too long, and it is important to use a recommended card.

if you are using the GPS mount and have enabled it on menu, 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 poor satellites reception. 

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.

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 and set parking timer for chance.

Please make sure if there are other devices that may consume the power.

The camera comes with essential accessories you need, such as a car charger cable, and GPS mount. 

Optional accessories include HK3 and fuse tap for parking mode, CPL to reduce reflections, Bluetooth Control for remote control, microphone and VIOFO original cards.
