Question: I put in a 64G SD card.  Now it just says "mass Storage".  What does that mean ?
Document: If you select Mass Storage, you can access the files on the micro sd card. The  problem is, you cannot cycle through the menu options until either the camera is charged and not connected to your computer, or connected to your vehicle's power outlet.
At this point, I replaced the class 6 SD card with a class 10, and will provide my review later.
Well, I used it for 2 weeks and it worked great then it stopped working. It's literally not worth the SD card I purchased nor the micro usb car charger and cable that came with it. I am very disappointed with this purchase and urge anybody to stay away from this product.
But it's done everything I need so far. It fits neatly behind my rearview mirror. It turns on and starts recording automatically when I start the car, and shuts off when I turn off the car. It saves the video on a (not included) micro SD card, in AVI format. The video quality is ok, but not great.
Have it for a bit more than 2 weeks. With the concern of the SD card compatibility issue that comes from the previous MY unit, I fitted this 2014 unit with 16GB class 6 micro SD. I have reviewed videos that were recorded both day and night, during sunny and raining days and I have to say that I am very happy with its performance.
So for that I'm thankful. However, the sensor did not detect any impact, and this was around 15 MPH, I would recommend purchasing a large SD card (32gb) so that you're able to recover the footage, without the camera deleting it. The controls are easy if you are tech savvy, it is easy to navigate through the menus after a few uses. I would recommend this camera if you've been looking around for a cheap, yet reliable one.
Could not believe the superb quality image from this dash-cam. Insert a micro SD card (8gb = approx 1.5 hours). Connected it to windshield via suction cup behind rear view mirror. Short USB cord plugs into a USB 12v adapter which I already owned. In my vehicle, 12v socket powers off when car ignition is off. Camera automatically begins to record when vehicle is started. Provides a recording consisting of short 3 min segments for the duration allowed by your SD card capacity.
Great features; was too bright/exposed but it is adjustable and works well now. Nice to have, fun on vacations. Plenty of time with a 16 GB micro SD card, we leave it on for hours.
These are much smaller than the picture leads you to believe. Its TINY! But wonderful none the less. So easy to set up and get going. Just insert the MICRO SD card (make sure it is a class 4 SD Card), mount it to your windshield and plug into cigarette lighter. EASY AS THAT! It turns on when you start the car and turns off when you take your keys out. Crisp clear images even at night!
Worked great for about two weeks. Then it started turning off at random times. Then one day I got a &#34;memory error&#34; message, which wouldn't go away even if I swapped out the MicroSD card with another one.
Answer: Did you hook it up to the computer? The computer will say "mass storage" when you attach your dashcam to it, that's how you transfer your video files off of it. I think there might be a size restriction on these dashcams as well, for mine it was 32gb.
