Navigon AG is $20 Off Through November 30th
This is $20 off the regular price and is now $30 cheaper than the TomTom app that is also available on the iPhone.In addition to the regular mobile navigator being on sale, they have also discounted the Traffic Live feature which is normally $24.99 down to $14.99. This really makes it attractive as you can have everything that they offer and still pay less than the TomTom all by itself.
