We suggest you choose VIOFO original cards, there are some other types you can choose from. 

Please refer to below pic for details.

We suggest you format the card periodically to ensure the best performance of the camera.

Here is a tool you can use for deep formatting.

The biggest difference between these products is the video resolution and recording range. You can refer to the following comparison blog for more details.

The standard rear cable length is 6M, and we have other lengths like 1/8/10M you can buy, we do not suggest extending the cable on your own.

Please note A129 Plus Rear Cable is unique and can not be used in A129 DUO/PRO dashcam.

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.

①Auto event detection: only record when it detects motion. 

②Time-lapse parking mode: record with fewer frames and no sound, video playback is fast and mute, less card storage consumed in this mode.
