We have improved the explanation about the data you share with TomTom, and the settings required for you to give permission and share data from your device. You can read more here.
•All supported devices now have an improved status bar with different tabs similar to most recent devices, and a clearer indication of the speed limit.
•If you use your device at about the same time every day your device will find your current location faster when you first start your device. This improvement is for all compatible devices except the GOx20 and GOx30 devices, and LIVE devices which get QuickGPSfix over the air.
• If you have a LIVE device and a valid subscription, speed camera locations, both fixed and mobile, are now delivered over-the-air.
