180 Infotainment system
Notice for updating contacts
• This function can be used with
mobile phones that support
contacts update and the call
history transmission function. (If
the product is connected to a
mobile phone that does not
support these functions, the call
history can be displayed through
the Infotainment system.)
• Update is not supported for more
than 1,000 contact numbers.
• Be aware that hands-free and
Bluetooth audio playback will be
cut-off while proceeding with
updates for contacts
(Other functions except for
hands-free and Bluetooth audio
playback can be used.)
• To update your contacts, it is
possible to request for the
transmission certification for
contacts. If the waiting screen
does not change for a long time,
you can check whether the
mobile is requesting for
certification. When requesting for
certification of the mobile phone,
all Bluetooth connections will be
cut off if it is not accepted, and
then the device will be
reconnected.
• When receiving the call history, it
is possible to request for the
transmission certification for the
call history from the mobile
phone. If the waiting screen does
not change for a long time, check
whether the mobile is requesting
for certification.
When requesting for the
certification of the mobile phone,
all Bluetooth connections will be
cut off if it is not accepted, and
then the device will be
reconnected.
• If there is a problem in the stored
information of the mobile phone,
the contacts may not be updated.
• The Infotainment system only
uses information coded in UTF-8
format.
• If other operations (game, map
search, navigation, etc.) are
activated during the contacts
update or call history
transmission progress, the
update/ transmission process
may not work.
This is because other operations
running on the mobile phone are
affecting the data transmission.
