All the VIOFO rear cables cannot be extended manually. The standard rear cable length for the A129 Series dashcam is 6M. 

If not long enough, you could buy a longer 8M rear cable here. A129 Plus Rear Cable is unique and is not compatible with A129 DUO / PRO model, pay attention when you purchase a new one..

① Replug the rear cable carefully. 

② Check if there are traces of damage around the port or pins.

if the rear cam is still gray in the live Video Source setup, you may need a new rear cable.

① If you use the original hardwire kit, check their connection first. use a multimeter to test, the ACC fuse port should be 0V when the ignition is off and the BAT fuse port has constant power whenever the ignition is on or off. 

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

② Use the original car charger or short cable to enter parking mode: Normally the camera will enter the parking mode automatically if no motion is detected in about 5 minutes.

Firstly, please make sure the hardwire kit is connected correctly, please set the low voltage protection rate to 12.4V/24.8V. 

If the low voltage protection does not work, please check if the ACC cable was installed right or not. 

Then you can set parking mode duration as you need, such as 2 hours, 4 hours or 8 hours instead of all day.

Most of such issue is related to the memory card, please format the card first. If that doesn't work, you can also try to replace it with a new memory card.

Two ways to reset the camera, by camera menu or by the reset hole on the camera body. 

① Press the REC light to stop recording and then press the menu button to choose the "Default setting" option. 

② Use a toothpick or a paper clip to stick the "reset" hole on the left side of the main camera.

Manual Locking: Pressing the triangle yellow button. 

Automatical Locking: When the G-sensor/Parking G-sensor is activated by a collision, its sensitivity can be adjusted from "low to high" .
