Users of the Bose BT2 headset will need to download and install firmware verison 1.05 to correct the pairing issue that effects the iPhone 4S (and possibly other models) that have been upgraded to iOS 5.1.


The firmware can be located on Bose's website at http://worldwide.bose.com/downloads/en/web/bose_bluetooth_system_overview/page.h tml


Once the firmware is downloaded, installed and then the headset is repaired with your phone, the connection issue should be fixed.


Common symptons (as I have experienced) are:


1. headset will randomly unpair and then repair itself with the handset even during a call


2. headset may only be partially paired with the phone, allowing the headset controls to function but will require that actual conversations will need to be done via the phone


3. Headset will periodically lose connectivity with the handset requiring that the headset be shut off then back on again


Apparently Blutooth upgrades in iOS 5.1 (support for v 3.0 +) causes problems with firmware 1.03 or older.

    Had to contact Bose to replace the headset under warranty because Bose & Apple could not determine what the problem was.


    The replacement unit has worked flawlessly, but in the past week I am seeing signs of the same problem starting up again and will have to monitor it carefully and see if Bose has another firmware update available that may resolve this issue.

    Try holding the talk button on the Bose for 5 seconds while in pairing mode especially on IOS 6.1 on later devices. iPad 2 and iPhone 5 worked for me. You couldnt even see the Bose Bt2 until then.
