What Causes a Dash Cam to Fail to Read the Memory Card?
3 Answers
If a dash cam consistently fails to read the memory card, it is likely due to memory card incompatibility. Below are the steps for using a dash cam: 1. Insert the memory card: Insert the memory card while the dash cam is turned off, then restart the device. 2. Install the app: Download the app on your smartphone by scanning the QR code provided by the seller or following the software name indicated in the user manual. 3. Connect via password: Before opening the app, go to the WiFi settings on your phone and select the dash cam's WiFi network (the WiFi name is usually specified in the manual and typically appears at the top of the WiFi list). Enter the password to connect (common default passwords include 12345678, 1234567890, 888888, or 8888888). Once inside the app, you can change the WiFi password—proceed with caution. 4. Successful connection: Once connected, you can use your phone to perform real-time functions such as recording, taking photos, playback, downloading, sharing, and system settings. This method is compatible with all Android and iOS devices.
Last time my dash cam couldn't read the card, it took me quite a while to figure out the issue. The most common problem is a damaged memory card, especially with those cheap ones that tend to fail after prolonged use. You'd better remove the card and try inserting it into a computer - if the computer recognizes it, then the issue is with the dash cam; if not, the card is likely damaged. Another possibility is that the card capacity is too large - older dash cam models might only support up to 32GB cards and won't recognize anything beyond that. Also, poor contact in the dash cam's card slot frequently occurs; I fixed mine by cleaning the slot with an alcohol-dipped cotton swab. Oh, and incorrect card formatting can also cause recognition issues - FAT32 format is more universally compatible, so if the card isn't damaged, try reformatting it to FAT32. One last potential solution is that your dash cam's firmware might need updating - downloading the latest version from the official website and flashing it could potentially solve the problem.
I've encountered several instances where the dash cam couldn't read the memory card. The type of memory card is crucial - regular SD cards may be too slow and incompatible, so it's better to use Class 10 or UHS-level cards. If the card lock isn't released, it can also cause reading issues; make sure the small slider on the side is pushed up. Prolonged operation without shutting down might cause the card to overheat and trigger protection mode - turning off the engine and waiting a few minutes usually resolves this. There's also the filesystem issue - dash cams generally can't read NTFS format. Remember to regularly format the memory card, ideally once a month, to prevent errors caused by fragmented file accumulation. Oxidation of the card slot's metal contacts is another common cause - cleaning the golden fingers with an eraser works quite well.
