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

General

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 mobile phone model will offer the same result. Some functions may require operations from the mobile phone. Refer to the mobile 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 JVC head units display. All characters may not be displayed in all cases. Depending on the setting or status of the connected mobile phone, some functions may not work properly. For example on certain mobile phones, making a call via JVC head unit is possible only while the mobile phone's display is showing the standby screen. All functions related to Bluetooth depends on the mobile phones connected with JVC head unit.

Pairing

JVC head unit may not be located depending on the signal condition or mobile phone setup. If the display show "Pairing error." and so on after the Pairing process is not completed Pairing has failed. If so, please retry Pairing after deleting the Pairing on both the JVC unit and the device to be connected. On certain mobile phones, PIN (Personal Identification Number) code is fixed. (e.g. "0000") The pairing and connection process depends on the mobile phone. Please check the operation of your mobile phone in advance.

Connection

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 mobile phone or turning the power off and then turning on again for both the JVC unit and your mobile phone. Connection status displayed on the JVC head unit is not necessarily correspond to that of the connected mobile phone.

Dialing, Receiving (HFP)

Noise or loud echo may occur during a voice call. On certain mobile phones, Switching Conversation on HFP (between head unit and mobile phone) may not work properly or noise may
occur when switching. JVC head unit and mobile phone may not always match up properly (e.g. mobile phone doesn't cut the line even if the JVC head unit ends the display of call function, etc.). On certain mobile 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. ""+"" simbol may not be displayed depending on the mobile phone.)" Call-waiting is not supported. Some mobile phones can not reject an incoming call because the mobile phone does not support the function.

Phonebook Function

On certain mobile phones, Phonebook and Call History may not be identical between those of JVC head unit and mobile phone. (e.g. "+" simbol may not be displayed depending on the mobile phone.)
If your mobile phone supports OPP, it is available to transfer your phonebook data from the mobile phone to JVC head unit manually. The following operations are necessary to initiate/terminate phonebook transfer: 1. Set the receiver to the transfer-wait mode (screen display example: "Please send phone book data from your phone."). 2. Use the mobile phone to transfer the phonebook entries you desire (individual entries, groups, and/or the entire phonebook can be selected and transferred; actual operation may vary depending on the type of mobile phone used). 3. Terminate the transfer-wait mode from the receiver (when maximum memory capacity is reached, the receiver will automatically terminate the transfer-wait mode).
Before transferring phonebook data via OPP, some mobile phones need deleting the Pairing on both the JVC head unit and the mobile phone. Text characters of phone numbers that can be recognized on JVC 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. Even if your mobile phone supports PBAP, it may be not available to access the phonebook/call history data memorized in your mobile phone or SIM card depending on your mobile phone's specification. And, after HFP connection is established between JVC head unit and your mobile phone, it needs some time to be available to browse the phonebook/call history data on JVC head unit automatically depending on your mobile phone and the number of phonebook/call history. International call may not be done from phonebook/call history of JVC head unit.
Battery remainder/ Signal strength indication
Signal strength indication and battery remainder indication do not necessarily correspond to those on the mobile phone.

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 mobile phones compatible with HFP only may stream music data. In this case sound quality is low. 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. During Bluetooth audio playback, when the sound is interrupted by a call reception, call making, playback may not resume automatically even after interruption ends. There may be cases where sound cannot be played from the JVC head unit even though the music is being played back on the mobile phone. To prevent distortion or static noise, adjust the volume level on the wirelessly connected device before use.
