Just bought navigon 1.6 for the iphone 4 (very nice app!) and the live traffic extra. After I put in my route and then go to options and then Traffic messages, I get a red bar that says offline and below that no traffic message are present. Is there a secret to make this traffic add on work or make it go on line? I have restored the phone completely reinstalling the app along with the traffic extra and have made sure that my data roaming is on.
