Mercedes-Benz Australia has just released some of their services such as the navigation package as a monthly fee instead of just the 12 month or 36 month options. If you wanted to update your maps you would generally pay for the 12 month service around $206. Now however, it's $20 per month and you can cancel anytime which still gives you the latest map update downloaded to your car.
The best part is the first month is free!
$20 a month, for the latest map? Is that all?
