Updating the Bluetooth ECU on earlier vehicles will improve pairing on more recent mobile devices. It
will also allow phone book access on the radio or navigation screen. It is not necessary to proceed with
this update if these features are already working properly.
Note:
This update will only work on units with pairing code 2121. The dealer fitted kits (pairing code
0000) cannot be updated.

Instructions
Notes on mobile App usage:
Once started, the re-flashing process is independent from the App and
is only handled by the IIDTool. The App is only used to display the current status and can be left in the
background, foreground or closed. If the mobile device gets disconnected from the IIDTool, voluntarily
or not, the App will recover automatically once reconnected to the IIDTool.
Steps
L322-2005 and L322-06
• Select the Bluetooth re-flash and follow the instructions on screen.
• The process is done with the key to the Accessory position (I). Make sure that the headlights are
turned off and that any unnecessary lights or accessory are turned off also.
• Upon completion, turn the key to the ON position (II) and follow the instructions on screen.
L319-04 and L320-05
• Select the Bluetooth re-flash and follow the instructions on screen.
• The process is started with the key to Ignition, position II. Once re-flashing has begun (indicated
on the Navigation screen), the key can be removed. It can also be left in position II in which
case the user should keep an eye on the vehicle and wait until completion (the instrument pack
will wake up). Failure to turn the key to the OFF position after the procedure is completed (or if
a failure occurred) will lead to a battery drain if not connected to a power supply.
• Upon completion, turn the key to the ON position (II) and follow the instructions on screen.
Keep an eye on the vehicle and wait until completion (the instrument pack will wake up). Failure to
