Important Notice for Bluetooth Operations

The following is a list of things you should know including various potential issues when using Bluetooth functions. Be sure to read it.


Since Bluetooth is wireless communication, there may be cases where normal communication is not available depending on signal quality.

Compatibility status shown above is applicable to the unit that we have used for the test. This does not guarantee that all units of the same cell-phone model will offer the same result.

Some functions may require operations from the cell-phone. Refer to the cell-phone's instructions for details.

Model names or model numbers are trademarks or registered trademarks of their respective holders.

Connection with a PC is not supported.

Number of characters available for each information display depends on the KENWOOD head unit's display. All characters may not be displayed in all cases.

Depending on the setting or status of the connected cell-phone, some functions may not work properly. For example on certain cell-phones, making a call via KENWOOD head unit is possible only while the cell-phone's display is showing the standby screen.

All functions related to Bluetooth depends on the cell-phones connected with KENWOOD head unit.


KENWOOD head unit may not be located depending on the signal condition or cell-phone setup.

KENWOOD head unit may not be able to be located during while Auto Connect is enabled. In this case, try again after setting "Auto Connect" to "OFF".

If the display does not show “Connected” or "Pairing Completed" after the Pairing process is completed, Pairing has failed. If so, please retry Pairing after deleting the Pairing on both the KENWOOD unit and the device to be connected.

While establishing Bluetooth connection with one cell-phone, pairing with another cell-phone may fail. In this case, try again after disconnecting.

On certain cell-phones, PIN (Personal Identification Number) code is fixed. (e.g. "0000")

The pairing and connection process depends on the cell-phone. Please check the operation of your cell-phone in advance.

Paired device name may not display properly.

Compatibility Check Mode will not work if Bluetooth connection has already been established with another cell-phone.

Compatibility Check Mode only checks the connection of Bluetooth profiles, and does not guarantee all the functions of Hands-Free Call and Audio Streaming features.


There may be cases where automatic connection is not established properly even if "Auto Connect" is set to "ON". In this case, try again after confirming the settings of your cell-phone or turning the power off and then turning on again for both the KENWOOD unit and your cell-phone.

Connection status displayed on the KENWOOD head unit is not necessarily identical to that of the connected cell-phone.

When the unit that is connected to phone A over HFP and phone B over HFP/A2DP/AVRCP is turned off and on, the unit and two phones are reconnected automatically thanks to “Auto Connection”. However there is a case where the unit is connected to phone A over HFP/A2DP/AVRCP and phone B over HFP depending on types of cellphones.

Dialing, Receiving (HFP)

Noise or loud echo may occur during a voice call.

On certain cell-phones, Switching Conversation on HFP (between head unit and cell-phone) may not work properly or noise may occur when switching.

KENWOOD head unit and cell-phone may not always match up properly (e.g. cell-phone doesn't cut the line even if the KENWOOD head unit ends the display of call function, etc.).

On certain cell-phones, the other party's phone number and name may not be displayed properly at call reception, while talking, or while talking to a call-waiting caller. (e.g. Plus sign (+) may not be displayed depending on the cell-phone.)

Unintended Call-Waiting action may occur.

Some cell-phones can not reject an incoming call because the cell-phone does not support the function.

When phone A and phone B are connected to the unit over HFP, and phone A receives a call, phone B is disconnected. After phone A’s call ends, phone B is reconnected to the unit over HFP automatically. However it may not be done correctly depending on types of cellphones.

During a hands-free call, if a cellphone supports “HPF Remote Audio Volume Control”, the unit’s audio volume can be controlled from the cellphone. However it may not work correctly depending on types of phones.

Ring Tone in Phone

The Ring Tone that is played depends on the cell-phone.

Voice Dialing

There may be cases where voices cannot be recognized easily or operation is not stable depending on the cell-phone model or environment in a car. If it is difficult to recognize your voice keyword, you can control microphone input level or noise/echo cancel setting on the receiver to improve.

On certain cell-phones, the status of Voice Recognition between KENWOOD head unit and cell-phone may not always match up properly.

When phone A and phone B are connected to the unit over HFP, and phone A receives a call/voice interruption, phone B is disconnected. After the call/voice interruption ends, phone B is reconnected to the unit over HFP automatically. However it may not be done correctly depending on types of cellphones.

Phonebook Function

Depending on the mobile phone to connect, the wrong contact details and phone number may be displayed in the KENWOOD head unit.

On certain cell-phones, Phonebook and Call History may not be identical between those of KENWOOD head unit and cell-phone. (e.g. Plus sign (+) may not be displayed depending on the cell-phone.)

On certain cell-phone, call history may not be arranged in chronological order. In addition, type(Incoming, Outgoing, Missed) may not be displayed.

Text characters of phone numbers that can be recognized on KENWOOD head unit are numerals 0 to 9, + (plus), *(asterisk), a to d, A to D and # (pound) signs. Unrecognizable characters will be skipped; make sure the correct number has been displayed before making a call from the phonebook.

Phonebook and Call History in your using SIM card can not be accessed from KENWOOD head unit.

Even if your cell-phone supports PBAP, it may be not available to access the phonebook/call history data memorized in your cell-phone depending on your cell-phone's specification. And, after HFP connection is established between KENWOOD head unit and your cell-phone, it needs some time to be available to browse the phonebook/call history data on KENWOOD head unit automatically depending on your cell-phone and the number of phonebook/call history.

The indication update speed of the phonebook completely depends on your using cell-phone.

International call may not be done from phonebook/call history of KENWOOD head unit.

Battery remainder/ Signal strength indication

Signal strength indication and battery remainder indication do not necessarily correspond to those on the cell-phone.

KENWOOD head unit is not compatible with Bluetooth audio players' signal strength and/or battery remainder indications.

Audio (A2DP, AVRCP)

Sound may be interrupted or playback speed may vary. For example, during music streaming, the sound may be interrupted while HFP is connecting/disconnecting.

Some cell-phones compatible with HFP only may stream music data. In this case sound quality is low.

Some cell-phones may stream the key operation sound via HFP. In this case, this sound may interrupts music streaming.

When starting and ending the call, music or noise may be heard for a moment if music streaming is being done in the background.

During music streaming, the Key/Play Mode Controls or Displays related to AVRCP may not function as they should depending on the device or Music Player application.

During Bluetooth audio playback, when the sound is interrupted by a call reception, call making, or voice recognition operation, playback may not resume automatically even after interruption ends.

There may be cases where sound cannot be played from the KENWOOD head unit even though the music is being played back on the cell-phone.

To prevent distortion or static noise, adjust the volume level on the wirelessly connected device before use.

When the unit plays audio over A2DP, if a cellphone supports “AVRCP Audio Absolute Volume”, the unit’s audio volume can be controlled from the cellphone. However it may not work correctly depending on types of phones.

Whether “Tag Browsing” works or not depends on types of cellphones. The displayed order and line of texts may not be same as those of a cellphone. And there is a case where a cellphone phone may not work as you intended.
