What is the max SD card size?

BlackboxMyCar Updated by BlackboxMyCar

The VIOFO A139 3-CH accepts microSD cards up to 256GB.

Please note that the A139 does not come with a microSD card in the box, so you will need to add one to your cart if you do not already have an existing microSD card. If you are upgrading from other VIOFO models (ie. A129 Plus, A129 Pro, A129), you can reuse the microSD card - just make sure to reformat it before using it in the A139.

When deciding which microSD card you need, keep in mind that the A139 3-CH records from 3 cameras so that's more files you need to store on the card.

How did we do?

How do I install the CPL filter on the A139?

Can I change the quality to 1080P for the front and get 60 FPS?
