You can check the status of your subscription at any time, by tapping TomTom Shop in the Main menu, then tapping Danger Zones.
When you have 7 days or less before your subscription expires, the TomTom app shows a message to warn you that your subscription is approaching the renewal date. This message is repeated when you have one day left on your subscription.
After your subscription has expired the Danger Zones service is deleted from the TomTom app.
The colour of the danger zone symbol in the Driving View indicates whether your Danger Zones service is connected to the TomTom server.
