®

difficult.
Song names cannot be recognized
by voice.
―
Cause
For about 3 seconds after starting a
®
call, the Bluetooth unit's Noise
Suppression function requires time
to adapt to the call environment.
The volume is set at zero or low.
Cause
The indication method is different
between the vehicle and the device.
The number has not been registered
into the phonebook.
Some types of cell phones do not
synchronize automatically.
Solution method
If there is any malfunction after
checking the pairing situation, check

problems.
By carrying out the following meas‐
ures, the rate of recognition will im‐
prove.
Clear memory from the phone‐

book which is not used very of‐
ten.
Avoid shortened names, use full

names. (Recognition improves
the longer the name is. By not us‐
ing names such as "Mom",
"Dad", recognition will improve.)
Guidance can be skipped by quickly
pressing and releasing the talk but‐
ton.
Solution method
This does not indicate a problem
with the device.
Increase the volume.
Solution method
If the number has been registered
into the phonebook, the incoming/
outgoing call record is updated by
the name in the phonebook when
the engine is restarted.

nization.
