The dash cam will automatically delete the oldest file and replace it with a new one, ensuring you have the most relevant data on the SD card. There are two reasons the dash cam will report this error message, either the SD card is not working correctly and cannot overwrite once its full or it has become full of protected files.

Check the SD card is class 10, between 8Gb and 128Gb, a recognised brand and not counterfeit. You can contact our Technical Support Centre with photos of both sides of the SD card and we can assist you in confirming the above, the card manufacturer can also assist with this.

1. Connect the dash cam to the 12v socket in a vehicle using the cable supplied and turn on the vehicle ignition.
2. If the blue LED lights up then the cable is working correctly. Disconnect the dash cam from the power cable and remove the SD card from the dash cam. Then push the reset button (usually located on the underside of the dash cam) and then reconnect the power cable with no SD card inserted.
3. If no LEDs light up then there may be a problem with the Power cable. Please try using an alternative power supply (e.g. USB cable with mobile phone plug).

1. If the dash cam does not record automatically then there may be a problem with the SD Card. Firstly try formatting the SD card using the option in the dash cam Settings Menu accessed by pushing the tapping the LCD and then the cog.
2. If Re-Formatting the SD Card does not resolve the problem then try removing and re-inserting the SD Card.
3. If Re-inserting does not resolve the problem then please try using a different Micro SD Card.
4. If the SD card is not the cause of the fault, confirm the dash cam is on the latest version of firmware on our website.

1. Try testing the dash cam using the supplied 12v Car power cable with the 12v socket in a vehicle. If this works correctly then there may be a problem with the installation of the Hardwire Kit. Please ensure that the Hardwire Kit has been earthed correctly to an unpainted part of the vehicle chassis, try a new earth position if you still receive no power.
2. Connect the hardwire kit directly to the battery terminals to see if there is anything wrong with the cable.

Please remove the SD card and any power cables, then press reset button until it clicks.

Then with the SD card out, press and hold the on button for 5 seconds, this should reset the unit.

GPS signal can be inhibited by other devices and systems in a vehicle (e.g. heated front windscreen). Please test the dash cam outside to see if the problem remains. The GPS receiver is located inside the mount for some models, please test a new mount if the dash cam doesn’t connect outside of the car connected to the mounting.

Please ensure that you have the latest version of Nextbase Replay 3. This can be downloaded from the Nextbase website (www.nextbase.co.uk). Please note that the minimum recommended requirements for Replay 3 are Windows 7, 8, 8.1 and 10 or Mac OS X 10.9 or higher, Processor: Intel Core i5, Memory: 4GB, Display resolution: 1280 x 720 or higher.

If videos are still not playing correctly please check that the videos play back correctly on the dash cam itself using Playback mode. This is usually accessed by pushing the Mode button twice.

The calculation of speed is based upon GPS position and hence distance travelled over time taken. This is a complicated algorithm and there may indeed be some discrepancy between devices, as it is a calculated speed, not an actual speed as measured by your road wheels.

In our tests, once multiple satellites have been located the speed is accurate to within 5%. Normally however, vehicle manufacturers always tend to be optimistic in their display of speed.

1. Download the Cam Viewer App from the relevant App store for your device (Apple App store or Google Play store).
2. Turn the dash cam on by connecting it to power.
3. Press the Wi-Fi button until it clicks to turn on the Wi-Fi then go to Wi-Fi settings on the mobile device.
4. Enter the password that is displayed on the screen 12345678 (or whatever you have changed it to) and tap join.
5. Once connected open the Cam Viewer app, to view the files you have recorded tap on View Dash Cam videos. To download them: Android – press and hold on a file in the list and then select the down arrow when it appears, you can then select the files you would like to download and tap done. iOS – tap the down arrow bottom left when it appears, you can then select the files you would like to download and tap done.

Once downloaded, the files are stored inside the App in the downloaded videos folder, from here they can be shared.

1. If updating manually via the SD card reader on the computer please ensure when you’re connecting power to the device don’t use the computer, it must be a car charger or mains plug adaptor and USB cable.
2. Check the firmware file name hasn’t been renamed, it must read: FW380GWA.bin

Note: If you’re using Nextbase Replay 3 on a Mac operating system, you cannot update via the USB cable it must be done via a card reader.

1. Angle the camera so that there is 70% road, this helps ensure that the part of the road where the action would happen is always correctly exposed.
2. Check the firmware version is up to date and that you’re viewing the high resolution file.
3. If you have a polarising filter fitted, ensure its correctly angled to remove dash board glare. To do this place a piece of paper on the dash and swivel it until the reflection disappears.
4. Check the resolution setting, the higher the resolution the more detail is captured per frame.

Yes especially with the HD files on the Nextbase dash cams, the continuous recording combined with continuous power causes the dash cam to heat up. Steps are taken within the dash cam design to ensure this heat dissipates as quickly as possible, therefor not causing any damage to the dash cam or SD card.

They are tested to up 50 °C, please note car interiors can exceed this if left in direct sunlight for prolonged periods of time.
