I have the TomTom Go app on my phone and have used that in my previous car for a couple of years. Since buying the XC40 mid 2019 I haven't used my phone app.
It reroutes well enough for my purposes, suggesting an overland route if my usual motorway route is impeded.
Real Time Traffic Information
First couple of times (in France & UK) we checked it against Google Maps, which is usually quite good at rerouting, and found that they agreed - so now we trust it to do the right thing. And trust is the main thing; you'll never really know if the rerouting works out for you every time, but you'll feel better.

Thanks, good to know I won't have to mess around with getting NAV via my phone or TomTom like I do in my V40.

Anyone else think that the display is a bit bland? It could do with a bit more colour and more topographical features shown IMHO.
