・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.
