Hello, I bought my A229 a few weeks ago. A week later I purchased the 128gb memory card from viofo website. Initially, I was using Garmin 66w with a 200gb sandisk ultra (see photo). I used the 200gb old card for about 2 weeks before the viofo one arrived and got 'memory card slow' error 2 times in that period. When the new card arrived I put it in the dashcam and formatted it immediately. On the 2nd day of using the memory card (i.e. today) I got 'memory error' 2 times (with beeping) after starting the vehicle. I am surprised as I thought the viofo card would work well with their dashcam. I have done a speed test and both cards have the same exact speed. How can I fix this? Anyone out there using the A229, which memory card do you use that doesn't have issues?
