if it plans you a route round traffic then it would be useful if it t drives you into the jam then what exactly are you paying for?
Genuine Q I have never heard of the system
Most sat navs use the TMC system which is basically radio and highways agency data, useful but often a bit historic. The LIVE system on Tom Tom (I think) uses data from other Tom Tom users on that route, i.e. average speeds etc and combining that with HA data either informs you fairly quickly of a problem and re-routes or it gives accurate data of the delay.
It has been very handy having it and to be fair I’m probably answering my own question, my shick was the price of it, but they know it’s good and in the main it’ll be used by company car drivers who will put it on their expenses… *coughs 😆
I have google maps and HA app on my phone but they tend to be uselss on saddleworth moor stretch of M62..
