Frequently Asked Questions

You can check this on the CamViewer mobile app or Replay3 computer app. 

Please check that your CamViewer app is on the latest version available and that your phone has Wi-Fi turned on.


If you require any further help with an app issue, please contact Nextbase Support at [email protected], Live Chat or 02920 866429 (UK).

Please check that your card is not larger than 128GB and has a minimum U1 class.
Please remove the SD card, then press the reset button on the Dash Cam. Then, without the SD card inserted, please turn on the Camera. Does it now start normally? If so, then the SD card has either failed due or is not compatible for Dash Cam usage.

Plug the USB cable into the camera. The camera will go into Mass Storage Mode and the red Protect Button should flash. 

To connect the Dash Cam in Update mode, press and hold the Protect button during connection
of the USB cable. Release the button once the Wi-Fi button flashes blue.

The Series 1 and Series 2 Hard Wire Kits will work with the Series 1 model Cameras. The Series 2 Hard Wire Kit is backwards compatible.

Regarding the recording lengths, the camera will record continuously in small segments. It will record these segments consecutively until the SD card is full. Then the oldest piece of footage will be deleted, and the newest will be saved in its place. This will continue looping and is called Continuous Overwriting. The Dash Cam does this automatically to allow for more footage to be recorded and the old, unnecessary footage to be deleted without manual intervention. However Protected Files are not overwritten in the same way. These can build up and prevent normal footage from being recorded. It is crucial to format every 2 weeks to delete any built-up footage.

Red: The red LED has three functions, as described below:
Power- The LED will be illuminate when power is connected to the Dash Cam.
Recording- During recording the red LED will flash.
Firmware update- During the firmware updating process, then red LED will flicker.

Yellow: This yellow LED indicator will flash (quickly) during formatting of the SD card.

Your camera is in Mass Storage Mode when plugged into your computer. The red exclamation mark button will flash to show that you're in computer Mass Storage mode. In Mass Storage Mode you can view and save your dash cam footage to your computer. 
If you need to update your camera instead, please see the FAQ above 'How to connect a 300W in Update Mode to a computer'. 

Any spare parts can be purchased from the below website:

The 300W does not have a compatible rear camera. We would recommend using a separate Camera such as the 122 or 222 on the rear windscreen. You will need a separate power supply and SD card as it will not connect to your 380GW, but can be used as a Camera facing rearwards. The prices are comparable with the Series 2 Rear Cams, and if you’d like to keep using your 300W, is the most viable option.

It is crucial to format every 2 weeks to delete any built-up footage.

1) Plug your Dash Cam in. Ensure the cable is plugged directly into the dash cam . If it does not appear as a drive on your PC, please try all the USB ports on your computer.

2) Then the Dash Cam will be visible as a removable drive on your computer. If you go into My Computer (Windows) or Finder (Mac) you will be able to see the Dash Cam listed as a drive, usually called NEXTBASE.

3) The Dash Cam should now flash red in Mass Storage Mode. Double click on this drive. You should then see nextbase.com, nextbase.info and DCIM.

4) Double click on 'DCIM'. Inside this you'll see a selection of folders. Inside these folders are your photos and footage.

5) You can copy the files onto your PC to save, view them using your computer's media player, or view the files using the correct Nextbase app. For the 300W this is Replay3, which can be downloaded above.

The maximum compatible SD card for the 300W is 128GB. We would recommend a Dash Cam compatible 8GB-128GB U1 Micro SD card, specifically designed for Dash Cam or CCTV usage. We would recommend a Nextbase SD card for guaranteed functionality within a Nextbase product.

You can re-format the card by two methods;

1) On the Dash Cam Itself
2) On a Computer

1) On the Dash Cam:
a) Turn on the Dash Cam (by plugging into power).
b) Stop it recording (press the red circle button once).
c) Press and hold the red exclamation button for 5 seconds until the yellow LED begins to flash.
d) Once formatting is competed the LED will stop flashing.

2) Using the CamViewer App
a) Open 'Dash Cam Settings' from the CamViewer home screen by tapping the menu button.
b) Select 'Format SD Card' and follow the on-screen instructions.

Please be aware that formatting the SD card will delete all the data on the card, so if you wish to keep any footage, please copy this across to a computer before you start the formatting process.

We recommend reformatting the SD card every 2-3 weeks to prolong the life of the card.

The Red round button with a power symbol underneath is the Power button.
Power: Press and hold the button for 2 seconds to turn on and off the Dash Cam.

beep sound will also be when ‘Sounds’ are enabled.
Once turned on, the button will flash slowly blue in colour, awaiting a connection from a
smartphone / tablet etc.
Once a device has been successfully connected the button will become solid blue.
If a connection is not established within 2 minutes, then the Wi-Fi function will turn off
automatically and the blue flashing light will extinguish.
