Title: how does the satnav know about congestion when no data connection
Post by: nigeldodd on 20 July 2018, 21:09
I have a 7.5pp and no fancy audio or nav. I sometimes use Google Maps on Android Auto but this question is not about that, it is about the built-in satnav.

Now I understand that you can get live traffic if you link the built-in satnav to a data connection, but I have not done that. However today, coming back to Cheltenham from Bristol it told me in Bristol that there was congestion on the M5. How could it possibly know this?

Its knowledge is pretty accurate so worth paying attention to.
It also 'knows' about traffic congestion in France Spain etc.


I expect it knows is because it is very well connected  :whistle:

It’s through DAB, if you go on traffic I’m sure it tells you the source of the data somewhere.
