Mio P350 - Manual (Page 63)

4.8.2.5 Use traffic information
This button is enabled by default, which means that TMC messages are used in
route planning. Tap this button to have Mio Map ignore real-time traffic information
when planning routes.
Tip: If you are setting up a route for a future journey, it may be better to turn off TMC.
4.8.2.6 Recalculate to avoid traffic
This setting is similar to the previous one. Disabling it will not prevent the system
from using TMC data for route planning, but will not trigger an automatic recalculation
when the traffic conditions change during your journey.
