Performance Box Touch has an inbuilt track database with circuits throughout the world, you can find a list of the currently supported circuits here.
The unit will display the currently selected track based on the GPS location. If multiple layouts are available, you can press the Select button to scroll through the different options. To choose a layout, press the desired option and press the Confirm button at the bottom right of the screen. If you wish to return to the Settings screen without saving, press the Cancel button at the bottom left of the screen.
Note: If you press the Select button when you are not in the vicinity of a known track, the unit will display a NO LIST AVAILABLE message.
If the layout has changed, the LEDs will briefly flash green twice and the unit will emit an audible confirmation notification. The layout will be remembered after each power cycle if it is determined to be local to the detected location.
Note: When the selected track is changed, all existing lap timing values will be cleared and new lap timing gates will be used.
