The time taken to
calculate a route
sometimes seems
longer than usual. This phenomenon is normal. The system is

The performance of the system may slow down tempora rily if a CD is
being copied onto the Jukebox at the same time as a route is being
calculated. Wait until the CD has been copied or stop the
copying before starting the guidance function.
Does the emergency call
function work without a
SIM card? No, European regulations impose the presence of a S
IM card in order to
make an emergency call. Insert a valid SIM card in the slot on the RT4 GPS
audio/telephone.
My SIM card is not
recognised. The RT4 accepts 3.3 V SIM cards, the old 5 V and 1.
8 V SIM cards are not
recognised. Contact your telephone operator.
After changing a wheel,
the system loses its
location. The RT4 GPS audio/telephone uses the wheel rotation
information to
i m p r o v e t h e G P S l o c a t i n g f u n c t i o n . I f a w h e e l i s c h a n g e d o r d e l a t e s
suddenly, the system recalculates the location. For approximately ten
minutes, this recalculation may affect the quality of the locating function.Wait until the system has completed its
recalculation.
The table below groups together the answers to the
most frequently asked questions concerning the RT4 audio/telephone.
The location on the
map is incorrect or
inaccurate.
The altitude is not
displayed. On starting, the initialisation of the GPS may take
up to 3 minutes to
receive more than 3 satellites correctly. Wait until the system has started up completely.
Check that there is a GPS coverage of at least
3 satellites (long press on the MENU button, then
select AUDIO/TELEPHONE DIAGNOSTICS, then
G P S C O V E R A G E ) .

the conditions of reception of the GPS signal may v ary.This phenomenon is normal. The system is
dependent on the conditions of reception of the
GPS signal.
