De-authorizing (de-registering) a Bluetooth® device
Mercedes-Benz USA, LLC recommends deauthorization in both COMAND and the Bluetooth® device, e.g. the mobile phone.
Subsequent authorization may otherwise fail.
In the Bluetooth® device list, select the
authorized device by turning 
the
COMAND controller.
Select Options by sliding 
the
COMAND controller and press 
to
confirm.
Select De-authorize and press
to
confirm.
A prompt appears asking whether you really wish to de-authorize this device.
Select Yes or No and press to
confirm.
If you select Yes, the authorization for the device will be revoked.
If you select No, the process will be aborted.
If a Bluetooth® device has been deauthorized
and is out of range, when a new
search is carried out it will not appear in the
Bluetooth® device list.
