I agree with Jancko.
I have igo Nextgen 9.18.27.719974 installed on my TomTom 8375 which is a android device with TomTom truck installed on it.
The traffic info i get from TomTom is much more up to date then the traffic info i get when i use Igo on this device.
Both Igo and TomTom use a server to get traffic info from i asume?
But now i undertand that in fact that the info which is given by Igo comes from a server that made the TMC info digital to use with a mobile connection.
That explains why the info TomTom shows me is much up to date.
Igo mostly shows shows old delays which are not there anymore.
Because of that it calculates different routes if the delay is longer than 10 min ( this time i set in the igo settings )
