To celebrate 2 million smartphone owners of its satnav apps, Navigon is discounting its iPhone and Android apps by 50% until 13th February. Add-ons such as live traffic info and 3D panorama views are reduced by 25%.
So MobileNavigator for the iPhone is £16.99 for the UK version and £27.99 for the European version. For the Android, MobileNavigator UK is £25.47 and MobileNavigator Europe is £38.22.
I believe that the difference in price is because on the iPhone version you have to pay extra for full 7-digit postcodes (£1.19 with the 25% discount), traffic (£11.49) and a panorama view (£5.49). I think that these may be included in the Android version.
Reviews appear to be mixed.
