o If the kit has worked before, a soft reset of the phone will most likely fix
this. A soft reset can be done by taking the battery out of the phone for a
few seconds and then putting it back in.
37. I have an external speaker and the volume is too low even when turned all the
way up. What can I do?
o If this is the case, the reason for the problem is a high impedance speaker.
It is recommended to use a four ohm six watt speaker. For more audio, a
lower impedance speaker (as low as 2 ohms) or two external 4 to 6 ohm
speakers may be used. Also, make sure the proper wires are used to
connect to the speaker. Only the white and white/black pair or the gray
and gray/black pair of wires from the black male pin connector (the larger
of the two connectors) can be used. The loose thin brown and white wires
are a 600 ohm / 750 mVrms, line level output and will not be able to drive
an external speaker. Also, the rear-channel outputs do not carry any phone
audio and therefore can not be used.
38. My radio stays muted even after a call has ended. What’s wrong?
o This is an installation problem that commonly occurs when the Parrot
Mute line is used to directly control a relay. All relays that are driven by
electronic boxes should have a common rectifier diode (1N4xxx series or
equivalent) placed across the relay coil with the stripe pointing towards
the battery. Without a protection diode to absorb the reverse EMF or
“kickback” when the relay coil current stops flowing, the Parrot mute
circuit locks up.
39. I want to use the Parrot Mute line to control a high current source. Can I do that?
o It is recommended that a diode-protected relay with a switching current of
250mA or less is used.
40. I want to shutdown an amplifier instead of muting the radio. How can I do that?
o Wire the front speakers between the amplifier and speakers and use the
two Violet/Black wires (RR- rear speaker circuit) to interrupt the vehicles
Amplifier Enable line. For this configuration to work, the Violet wire
(RR+) should not be connected to anything. It does not matter which
direction the signal goes through the Parrot Mute Relay assembly because
the rear speaker circuits are only interrupted and not switched to phone
audio.
41. My car kit keeps losing all of its information after I turn my car off. What’s
wrong?
o This may be one of two issues:
Check to make sure that the fuse on the battery line is still good
and the battery line connections are still good.
Check to make sure that the battery line is in fact connected to the
battery and not also tied in with the ignition line.
This can be confirmed if your kit simply shuts off instead of saying
“Goodbye” on the screen before it powers down. When the kit says
“Goodbye” it is saving all the current settings, and when the wires
are reversed, it skips this step. Fix the fuses, and your issue will be
resolved
