*EDIT: to save others time, deleting the app off the phone and then reinstalling fixed my issue. Some one mentioned backing up your favorites before doing so.* I'm not sure if this is an app update issue due to iOS 6 (app was recently updated to work with iOS 6 but I hadn't tried it until today when I got my phone. It informed me there was a map update and to go to map manager to download the updates, but it gives me an error saying "An error occurred while registering your device. Please contact the NAVIGON customer service". Well unfortunately, their hours were already over by the time I saw this. But I try to go register, says my email is already registered (which is correct) and it asks me to sign, I sign in, says this device is already registered. App will not display the map, I can't input locations to get directions. Just a heads up to those who use NAVIGON heavily. You may want to either not update to iOS 6 just yet or keep using your older phone. Again I'm not sure what the issue is here. After I call NAVIGON tomorrow I'll try to remember to post back if they fixed it or not.
