Sign-in to your TomTom account – (ignore any “30-day trial” message)
Head to Settings > Account and you will see confirmation of your 1yr subscription for free.
If you have been assigned a free trial period, go to TomTom services and then log in there – should then be replaced with the annual subscription for free.
If issues
Install the application, then I chose the trial for 30 days. The next step I choose TomTom services and at the bottom is log in. I enter the email and password and the license from 30 days changes to a year.
Plus one account can be used on multiple devices , mine did not activate for a while but did 20mins ago as in the screen shots attached !
