Select: Function selector button NAV > function selector button SETUP > Set start location or Demo mode.
Enter your start location manually if, for example, you would like to calculate a route starting from a different position than the current position of the vehicle. Start the demo mode to simulate a route guidance. Use the demo mode to plan and display a route effectively by displaying map contents or route criteria.
Note
For safety reasons, the route guidance simulation (demo mode) is only available when the vehicle is stationary.
