Frequently Asked Questions
My dash cam won't turn on. What's the first thing I should check?
The most common culprit for a dash cam that won't power up is a simple power connection issue. Double-check that the power cable is firmly seated in both the dash cam and your car's 12V outlet or USB port. We've also seen instances where the car's outlet itself isn't working, so try plugging in another device like your phone charger to confirm the outlet is live.
Why is my dash cam suddenly not recording anything?
If your dash cam is on but not saving footage, the memory card is usually the problem. It might be full, corrupted, or simply incompatible. Try reformatting the MicroSD card; we recommend doing this at least once a month to keep things running smoothly. For 1080p cameras, a 32GB Class 10 U3 card is a good bet, while 1440p or dual-camera setups benefit from a 64GB Class 10 U3 card.
My dash cam keeps saying 'Check the memory card.' How do I fix this?
That 'Check the memory card' message almost always means the card needs formatting. Most dash cams have a built-in formatting option accessible through their menus, or you can do it on a computer with a card reader. If you're using a 64GB or larger card, it's crucial to format it directly on the dash cam itself for optimal compatibility.
The WiFi on my dash cam isn't connecting to my phone. What's wrong?
Dash cam WiFi is typically designed for close-range use, not for connecting to your home network. Make sure your phone is within a few feet of the dash cam after you've activated the WiFi on the device itself. Also, verify that your dash cam has a dedicated app for your smartphone (usually iOS or Android), as many don't support PC connections.
My dash cam overheats and shuts down in the summer. Is this normal?
Yes, overheating is a common dash cam issue, especially in hot climates or when parked in direct sunlight. Prolonged exposure to temperatures above 140°F (60°C) can damage the internal components. We've found that using a sunshade when parked or even temporarily removing the dash cam can prevent this.
I'm getting fuzzy or distorted video quality. What could be causing this?
Poor video quality can stem from a few things, including a dirty lens or a corrupted memory card. Wipe the dash cam lens with a microfiber cloth regularly. If the issue persists, try formatting your memory card or swapping it for a new, compatible one, as a failing card can also lead to recording errors and degraded footage.
My dash cam's GPS isn't locking on. What should I do?
A weak GPS signal can prevent your dash cam from locking on, especially if it's mounted low or obstructed. Try repositioning the dash cam to a spot with a clearer view of the sky, like the top center of your windshield. A quick power cycle - unplugging and replugging the dash cam - can also sometimes resolve temporary GPS glitches.
Why does my dash cam turn off when I turn off the engine?
Most dash cams are designed to power down with the ignition to conserve your car's battery. If your dash cam has a parking mode feature, it should automatically start recording when the engine is off, provided it's properly connected and powered. This feature is invaluable for capturing incidents even when you're away from your vehicle.
