Unpairing a V3 Razr from X5 with 2006 combo Assist/BT module

[discoball]

Hi - has anyone done this successfully? I followed the instructions in the owners/bluetooth manual and it's not working. I'm supposed to be holding down a button above my storage compartment while the key is in a certain ignition position. Only problem is that there isn't any button above my storage compartment. There's one on my steering wheel, so I tried that but I keep getting that voice saying "sorry". My phone has bluetooth enabled at all times and it's paired with the X5 just fine. I'm just not sure how to unpair it. There's a pic attached of the button I'm pressing on the steering wheel. Thanks!
