How to handle the dash cam prompting 'Please insert TF card'?

[VanMackenzie]

The dash cam displaying 'Please insert TF card' means: the TF card is invalid and needs to be replaced. Introduction to dash cam usage is as follows: 1. Most high-definition dash cams in the market default to 720p or 1080p. Remove the memory card from the dash cam, insert it into a card reader, then connect to a computer to read the contents. Search through the folders one by one. 2. The dash cam prompting a memory error is relatively common. If this occurs during initial use, it may indicate incompatible memory cards. Therefore, when selecting a dash cam, be sure to choose a compatible card. Dash cams have relatively low read/write speeds, which may cause such errors during use. It is recommended to use memory cards with C4 or higher speed ratings.

Last time I also encountered the dashcam prompting to insert a TF card. I simply removed the card and repeatedly wiped the gold contacts with an eraser, then reinserted it, and it worked fine. But remember not to use alcohol for cleaning—rubber erasers are the safest. If that still doesn't work, try using a different card reader on your computer to see if it can be recognized. Sometimes the issue is due to loose spring contacts in the card slot or the dashcam system acting up. When I had this annoying problem last time, it took me a while to realize the TF card was completely dead. After replacing it with a Samsung card, I never had issues again—this stuff really isn’t worth skimping on with off-brand products.

The dashcam popping up this prompt usually indicates three reasons: the TF card is not inserted properly, poor contact in the card slot, or a system recognition error. When encountering this issue, first completely power off and restart the device. During the restart interval, remove the card to check if there are any signs of oxidation on the metal contacts. Avoid formatting directly in the device; it's better to back up the data on a computer and then perform a full format. For older devices, it's advisable to check if they support high-capacity cards above 128GB—my neighbor just fixed his issue last week by switching to a new card. If all else fails, inspect the card slot pins. A mechanic suggested gently lifting them with a needle, which might yield a pleasant surprise.

This prompt most likely indicates that the card is not properly inserted or there's poor contact. You need to press the card in until you hear a click for it to be fully seated. However, for devices used over two years, the spring contacts in the card slot can lose elasticity. Cleaning the slot with alcohol wipes using tweezers works well. I once encountered repeated card insertion prompts during northern winters, later discovering temperature differences caused plastic slot deformation. A 30-second low-heat blow dryer treatment fixed it. Now, I routinely check the card slot when cleaning the dashcam lens monthly – maintaining this habit has virtually eliminated recurrence.
