I have the latest infotainment system (Mazda Connect, not Mazda MZD Connect).
The roads with traffic problems received by the TMC are colored and extra icons are displayed on the nav map.
From the manual:
Press the commander knob with the map screen open to display the
menu, and select “Traffic Settings” from “Navigation Settings”.
2. Set either “Flow and Icons”, “Flows Only”, or “Icons Only” in “Show
Traffic Information”.
Road segments affected by traffic events are displayed with an alternate
colour on the map, and small symbols above the road show the nature of the
event.
You can check the list of received road event at:
Press the commander knob with the map screen open to display the
menu and select “Traffic” from “Travel Information”. The Traffic Event list
is displayed.
All the functions of the navigation system in my car work as described above.
I remember from both my CX-3 that this also worked in the same way in the older nav system.
