QUESTIONANSWER SOLUTION
Certain
  traffic   jams   along  
t

he route are not indicated
in
 
real
 
time. On
  starting,   it   is   several   minutes   before   the   system   begins   to   receive  
t

he   traffic   information. Wait
  until   the   traffic   information   is   being   received  
c

orrectly   (display   of   the   traffic   information   icons  
o

n   the   map).
The
  filters   are   too   restrictive. Modify
  the   settings.
In
  certain   countries,   only   major   routes   (motor ways...)   are   listed   for  
t

he   traffic   information. This
  phenomenon   is   normal.   The   system   is  
d

ependent   on   the   traffic   information   available.
The altitude is not
displayed. On
  starting,   the   initialisation   of   the   GPS   may   take   up   to   3   minutes   to  
r

eceive   more   than   4   satellites   correctly.Wait
  until   the   system   has   started   up   completely   so  
t

hat   there   is   GPS   coverage   by   at   least   4 satellites.
Depending
  on   the   geographical   environment   (tunnel...)   or   the  
w

eather,   the   conditions   of   reception   of   the   GPS   signal   may   vary.This
  phenomenon   is   normal.   The   system

Radio
QUESTIONANSWER SOLUTION
The
 
quality   of   reception   of  
t

he radio station listened
to
 
gradually   deteriorates  
o

r the stored stations do
not function (no sound,
87.5 Mhz
  is   displayed...). The
  vehicle   is   too   far   from   the   transmitter   used   by   the   station  
l

istened   to   or   there   is   no   transmitter   in   the   geographical   area  
t

hrough   which   the   vehicle   is   travelling.Activate
  the   "RDS"   function   by   means   of   the  
s

hort-cut   menu   to   enable   the   system   to   check  
w

hether   there   is   a   more   power ful   transmitter   in  
t

he   geographical   area.
The
  environment   (hills,   buildings,   tunnels,   basement   car   parks...)  
b

lock   reception,   including   in   RDS   mode.This
  phenomenon   is   normal   and   does   not   indicate  
a

  fault   with   the   audio   system.
The
  aerial   is   absent   or   has   been   damaged   (for   example   when   going  
t

hrough   a   car   wash   or   into   an   underground   car   park).Have
  the   aerial   checked   by   a   CITROËN   dealer.
I
 
cannot   find   some   radio  
s

tations in the list of
stations
 r

eceived. The
  station   is   not   received   or   its   name   has   changed   in   the   list. Press   and   hold   the   "List"   button   at   the   steering  
m

ounted   controls   to   update   the   list   of   stations  
r

eceived   or   press   on   the   system   update   function:  
"

Update   list".
Some
  radio   stations   send   other   information   in   place   of   their   name  
(

the   title   of   the   song   for   example).
The
  system   interprets   this   information   as   the   name   of   the   station.

a
 
very   long   wait

QUESTIONANSWER SOLUTION
There is a difference in
sound
 
quality   between   the  
d

ifferent   audio   sources. For
  optimum   sound   quality,   the   audio   settings   for   Loudness,  
A

mbience,   Treble,   Bass,   Volume   can   be   adapted   to   the   different  
s

ound   sources,   which   may   result   in   audible   differences   when

Telephone
QUESTIONANSWER SOLUTION
I
 
cannot   connect   my  
B

luetooth
 t
elephone. The
  telephone's   Bluetooth   function   may   be   switched   off   or   the  
t

elephone   may   not   be   visible. Check
  that   your   telephone's   Bluetooth   function   is  
s

witched   on.
Check
  in   the   telephone   settings   that   it   is   "visible  
t

o   all".
The
  Bluetooth   telephone   is   not   compatible   with   the   system.You
  can   check   the   compatibility   of   your  
t

elephone   at   www.citroen.co.uk   (services).
The
 
volume   of   the  
t

elephone connected
in
 
Bluetooth   mode   is  
ina

udible. The
  volume   depends   both   on   the   system   and   on   the   telephone. Increase   the   volume   of   the   audio   system,   to  
m

aximum   if   required,   and   increase   the   volume   of  
t

he   telephone   if   necessary.
The
  ambient   noise   level   has   an   influence   on   the   quality   of  
t

elephone
 c
ommunication. Reduce
  the   ambient   noise   level   (close   the  
w

indows, reduce the booster fan speed, slow
down...).
