When you slow down while driving on a motorway, there
is a chance that you are in a traffic jam so the software
offers you a detour using the next exit. The message shows
you distance of the exit and the difference in distance and
estimated time compared to the original route. You can
choose from one of the following options:
• Tap Dismiss or just ignore the message if you want to
keep the original route.
• Tap Preview to see the overview of the original route and
the detour to make the decision. You can accept the detour
as offered or increase the bypassed motorway segment
before accepting.
• Turn to the suggested new direction and the route will be
automatically recalculated.
Similar to the above possibility, alternative routes can be
suggested when driving on normal roads. The software will
select a different turn in the upcoming intersection and offers
you a different route for the next section of the route.
Your options are the similar as above but you cannot modify
the offered detour.
Parking at the destination may not be easy in city areas.
As you approach the destination, the software can offer
parking category Places near your destination (if POI data is
available). Tap the "P" button to open a top-down map with
the destination and the offered parking Places. Select one
and modify the route accordingly.
