Hi. How I can delete all entries in Address book at once?

 

The only way to delete the address book is to reset the system which also resets the balance of the system back to factory settings. Something that should normally only be done when you are ready to sell your vehicle

 

Sadly it also removes any music you've added to the music register.

 

What exactly it will remove? Address book,music,satelite stations...
What else?
