How does it know this?

SCP440 · 26th June 2016, 18:46

I travelled up to Aberdeen in my ZTT with its Navall3 on Friday and on route it told me there was a quicker route to avoid congestion, I accepted its advice and carried on. An hour later it gave me another option but I declined as I was on the M6 and didn't really want to go off route, oh boy did I regret that, 2 hours sat in traffic.

Today on my return trip the overhead warning signs said there were delays on the M6 and the Navall 3 gave me an option to avoid so I accepted, as I left the motorway the signs were warning of a 30 min delay, 10 mins later I rejoined the motorway just after the accident.

As it says in the title how does the Navall3 know there is traffic problems? My phone was not connected to it so it must get it from airwaves somehow.

A great feature.

It has TMC?? I didn't knew that this feature has build in, in the Navall3

No TMC on the Navall3 .
If it wasn't your phone acting as a personal hotspot then maybe it just picked up a free wifi signal.
Or maybe you have historical traffic switched on in the Primo menus and it just offered an alternative route which just happened to coincide with an actual jam

GPS signal from Satellite

it does not need to be connected to a hotspot and it`s just doing what it is supposed to do.
