I subscribed to xm traffic services and 70 % of the time it will show traffic , closed road and the like. But it had been a few time when there was very heavy traffic the gps does not reroute me to another intinary like today for example i got stuck in traffic for 2 hours. My nagigation setting is set to retoute automatically.
I checked with Google maps and wave and both were rerouting to another route and shave 15mn of the planned route.
Is there a problem with the nav system not being able to calculate alternative route when in heavy traffic ? Otherwiaw i might as well cancel my subscription to xm traffic and use Waze or google maps
