Problem
Reason
Action
Interference occurs in the GPS
reception. The device receives
signals from the GPS (Global
Positioning System) satellite
system for precise positioning. If it
receives insufficient GPS signals
then it is not possible to make a
precise calculation from the
vehicle’s position to the
destination. (See also the point
”No GPS reception”.)
The signal strength of the GPS
can be read in the position display.
(See the ”More navigation
functions,” section ”Position
display ”.)
Use a map to find your way or
continue driving along the current
route
if possible. As soon as GPS
reception is improved, navigation
will proceed properly.
It is not possible to
enter the
destination’s
address
Entered postcode belongs to a
post office box (common for
business addresses). Such
postcodes cannot be used when
entering destinations.
Enter city name instead of
postcode. Take into account that
the same street name may be
used in several locations in some
major cities.
The street is new or the stretch of
road has changed but is not yet
included on the SD card with maps.
Find out whether there are any
newer SD cards with maps.
The calculated
route does not
meet your
requirements
User-set route options, e.g.
 Shortest or fastest route
 Motorway excluded from the
route
 Dynamic route guidance
(automatically bypass traffic
congestion)
Adapt route options according to
individual needs. (See the chapter
”Determining route options”.)
