TomTom No GPS Signal 2019
Since Saturday 6th April 2019 some devices have been having issues getting a GPS signal. The identified root cause for this problem could be the WNRO(Week Number Roll-over) issue which has caused some of our GPS models to not get a GPS position.
Read more about the WNRO on this topic-: https://discussions.tomtom.com/en/discussion/1108335/gps-week-number-roll-over
If you find that your device does not find a GPS signal it's important that you first check if your device is actually affected by entering the serial number of your device on this website:
If the message states that there is an update available then please connect your device to TomTom HOME or MyDrive Connect to check for updates.
Note: We started rolling out fixes for these since last year so you may already have the latest firmware installed.
Here is a list of previous firmware releases where you can quickly check if you have the latest firmware installed- https://uk.support.tomtom.com/app/release_notes/type/navkit
FINDING THE SOFTWARE AND MAP VERSION ON YOUR NAVIGATION DEVICE
GO LIVE 1000 series, GO LIVE 800 series, Via LIVE series, PRO 5150 TRUCK LIVE, Start series
You should have the latest version 12.075 installed on your device.
Some users may experience that the device does not connect to the satellites even when they have v12.075 installed.
It has been observed that it could take some time for the device to find a GPS.
1. Charge the device for a minimum of 2 hours.
2. Take it outside under the clear sky and do a soft reset(Press and hold the on/off button till you hear the drum sounds)
3. In exceptional cases, it could take anything between 30-45 min to find a valid GPS signal.( Keeping the device in a stationary position outside for a while does help)
Nav2 and Built-in devices updating through TomTom HOME -
ERROR- "You cannot use this map on this device" After the WNRO update-
Please post your concern on the below topic and one of the Moderators will help you get the map reactivated
Rider K4: After 06th of April this Rider model is unexpectedly not showing the correct time and ETA, while navigation is working as normal. We are currently working to see if an update is possible!
Some Nav2 devices, the timer will be reset to 00.00 and the ETA will also not show but the navigation will continue to work as normal.
Out of these, we are investigating if a fix can be rolled out and for some, we may not be able to release a fix.
If you wish to upgrade to a new TomTom then please contact customer service to avail a discount which you are entitled to as an existing customer.
Edit: 25th July 2019
We have released version 9.501 for Rider K4. The firmware should now be available in TomTom HOME.
Fixes for the below:
# RIDER not showing the correct time and ETA post WNRO(6th April 2019)
# Cannot record routes because of the clock reset issue.
I will be updating this thread as I get more information.
