Supported GPS Devices
Last Updated: October 15, 2026
Trackd can use an external GPS device over Bluetooth instead of your phone's GPS, for a faster and more precise position on track. The devices below are supported.
| Brand | Device | Update rate |
|---|---|---|
| RaceBox | Mini | 25 Hz |
| RaceBox | Mini S | 25 Hz |
| RaceBox | Micro | 25 Hz |
| Apple | iPhone (built-in GPS) | About 1 Hz |
Notes
- Update rate: This is how many position fixes per second the device sends. Your iPhone's built-in GPS is used automatically when no external device is connected.
- Connecting: Switch the device on and keep it close to your phone. A device you have used before reconnects automatically next time.
- Losing signal: If the device loses its GPS fix, for example in a tunnel, Trackd switches to your phone's GPS after a couple of seconds and switches back when the device recovers.
- RaceBox Micro: This is a bare board with no battery, so it needs its own 3.5–16 V power supply.
- Not connecting? If a device does not connect, please contact us and tell us the model.
- Trademarks: RaceBox is a trademark of its respective owner. Trackd is not affiliated with or endorsed by RaceBox.
