What I did was turn on BT on the iPhone. From the home screen: Settings > General > Bluetooth. Setup the headset to be discoverable (push and hold the button on the HS700 until the ring turns blue. Extend the boom mic. I believe you do the same on the HS850.) iPhone finds the headset. Enter the code for the headset. Mine was 0000. I believe that's universal for Motorola BT headsets. Ba-da-bing, ba-da-boom. DONE.Awesome, thanks!
Do you know where to find instructions on how to pair them up?
i have just posted a problem with the hs700 bluetooth and iPhone. try to call someone using your bluetooth, tap the button you will not hear nothing everything is manual not like the other phones where you will hear a response after tapping the bluetooth headset like say a name or number. you will not hear this with iPhone infact you will hear nothing. how does your's work? this will create a problem while driving and wanting to make a call using your bluetooth.I'm using my HS700 with no issues.
