The Home destination can be used to quickly set up a route back to home from any location.

Select Home > Nav > Where To.
Select Home.
Home has been programmed: The system calculates a route to the home destination. Select Go. Home has not been programmed: Select a home destination (address, recent destination, or so on). The destination will be used for all future home routing. To save your current destination as home, see Navigation → Saving Current Location.

NOTE

To delete or change the home destination, activate a route to home and select the option button on the map. Select Delete Destination. Repeat steps to program a new home destination.
Once a home address has been saved, a voice command can also be used to navigate home. Press the VOICE RECOGNITION switch and say HOME into the microphone.
