The Tilsberk app will ask you for the following permissions. Please note that these are necessary for trouble-free operation.
Bluetooth
The data is transferred between the app and Tilsberk head-up display via Bluetooth. It is also possible to transfer voice prompts to your Bluetooth headset via Bluetooth.
Location data
The current (exact) location is needed for the head-up display to show you the way and to determine the current speed.
Phone status (optional)
If you enable the phone status, the head-up display can show you who is currently calling you. If you do not authorize this, you will not be able to see any call notifications on the display.
If you notice functional restrictions during use: Please check which permissions you assigned when (initially) installing the app. You may have to adjust them again. Then check whether the functional restriction still occurs.
