Are you having issues with your CBX20 or CBX30 device? In this post, we’ll go through the most common problems:

My CBX20 or CBX30 no longer turns on.
If your device suddenly won’t power on, try a reset as the first step. Hold the power button for 9 seconds while the device is connected to the charging cable.
Still not working? The battery or charging cable is likely faulty. To make sure that the charging cable is working properly, you can test it with a voltmeter if possible.
To replace the battery, we recommend ordering our repair kit, which includes a new battery and hard case. Please carefully follow our instructions for replacing the battery. Alternatively, you can send in your device for inspection. To do so, please complete our return form and include it in your parcel. Also, send your charging cable along for inspection.
If your device is still within the 1-year warranty, contact us at support@crossboxapp.com.

My CBX blinks orange continuously and does not show a green LED light any more.
If there’s no green LED light, place your powered-on CBX under open sky for 3–5 minutes. If the green LED still doesn’t appear, the GPS module is most likely defective. This cannot be repaired and the device must be replaced.
In this case, we can offer you a replacement device for €120 plus VAT and shipping. The defective unit will be locked and can no longer be used. Please contact us at support@crossboxapp.com.
The GPS is very inaccurate or only partially works, even though the LED is green.
There can be several causes for inaccurate GPS:
- In most cases, the CBX is not positioned correctly. The flat side of the tracker must face upward (see image). This ensures the internal antenna is pointing toward the sky. Also, avoid mounting the CBX where it’s covered by the rider’s body. For best accuracy, we recommend mounting the CBX on the helmet.
- There may be interference nearby, such as large buildings or mountains. Try recording sessions in different locations to see if the issue is location-specific.
- The GPS module may be defective. If you’ve confirmed correct placement and no interference, contact us at support@crossboxapp.com for further assistance.
My CBX is not visible in the Crossbox App.
The CBX Tracker uses Bluetooth BLE, meaning it will only appear in the Crossbox App and not in your phone’s Bluetooth settings. Try the following steps:
- Restart your smartphone
- Turn Bluetooth off and back on again
- Restart the Crossbox App
- Ensure you’re using the latest version of the Crossbox App
If your CBX still doesn’t appear, the Bluetooth module may be defective. This cannot be repaired and the device must be replaced.
We can offer you a replacement for €120 plus VAT and shipping. The defective unit will be blocked in our system and can no longer be used. Please contact us at support@crossboxapp.com
