GPS Week Number Roll-Over
The GPS Week Number Roll-over (WNRO) on 6 April 2019 may have an impact on GPS performance. If you frequently update your device there’s no need to worry!
- Current navigation devices (Nav4) are not impacted.
- Sports and Action devices are not impacted.
- Some older navigation devices (Nav3 = using to MyDrive Connect and Nav2 = using HOME) may be impacted.
We have already started rolling out fixes for this last year. If you frequently update your device, you will already have installed it.
On https://www.tomtom.com/en_gb/updates/ you can check if your device is impacted using your device serial number.
Without updating, these devices may experience some of the following issues:
- No time
- Frequent loss of GPS fix
- No GPS fix at all - navigation impossible
