Connect your TomTom (from firmware 10.110 or higher) to your PC and start MyTomTom (from version 184.108.40.206 or higher) from the shortcut in the tray (right down corner). Choose “Add community content”.
The files are now copied to your Tomtom. Now the most difficult work is done! You just need to activate your new POIs.
In your Tomtom menu deactivate at Main/Services/Speedcams the warnings (if Live Services are active).
