Bluetooth® UNIT REMOVAL/INSTALLATION

WARNING: This page is about a different car, the 2016 Mazda CX-3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • The audio unit determines the presence/non-presence of a Bluetooth® unit and records it based on the communication status when the ignition is switched ON (engine off or on) or to the ACC position for the first time after the negative battery cable is connected.
  • If the negative battery cable is connected while the audio unit has recorded the non-presence of the Bluetooth® unit and thereafter a Bluetooth® unit is installed, the installed Bluetooth® unit will not operate.
  • When installing or removing the Bluetooth® unit, always disconnect the negative battery cable, and after the servicing is completed, switch the ignition to ACC or ON (engine off or on) to allow the audio unit to record the presence/non-presence of the Bluetooth® unit.
NOTE:
  • The Bluetooth® pairing information recorded in the Bluetooth® unit cannot be written to a new Bluetooth® unit. Therefore, the Bluetooth® pairing information will be eliminated if the Bluetooth® unit is replaced. Before replacing the Bluetooth® unit, explain to the customer that the Bluetooth® pairing resetting is required.
