Every time you upgrade the firmware, you MUST clear ALL devices from BOTH the SMH10, phone (and SR10/SM10 if you use them.).
Be interested in seeing the pairing instructions they gave you. remember, next time you do a firmware update or get a new Iphone, you are going to need those directions again, hope you wrote them down.
Ok. Here it goes.
After making sure everything is updated with the latest firmware, clear all devices and the Sena from recognition.
Hold the phone button down for 12 seconds until the voice prompt says "resetting unit". Hit the phone button again within 3 seconds. It will then power down.
Turn unit on. Hold phone button down for 5 seconds and here the phone pairing prompt. Pair the Sena and phone. Hold the jog dial down for 5 seconds and here the device pairing prompt. Pair the Zumo. Then your done. When you cycle everything on the next time, the Zumo connection is prompted as "device connected".
