Live-Traffic does not work on Becker professional.6 with original Software 9.15.3.578281 (based on Primo).
When you try to find Live-POI you'll receive the message: "No connection could be made to the Server". So I think that they changed the URL to access to Live-Traffic and Live-POI or even blocked access to all IGO PRIMO based Software..
But why .? Nobody knows it ofr the moment except NNG....
