Actually best navigation solution ....

Since I can prevail constantly with TMC Plus somewhere or drive around meaningless, no longer existing congestion my Garmin, I looked around for a modern solution of the route guidance.

Because of the combination of offline map navigation and online traffic information, this is my opinion the best Navi solution.
There is therefore a download volume of an estimated 3 MB / 100km for the traffic information, you have enabled this. Which is a relatively high value, the pure online solution Waze may consume 20% more and thereby invites the maps in real time down.

Unfortunately, the software does not start on any device, the route guidance. Läufts on my phone, on the tablet it denied the route calculation.
