I am unable to connect my h700 to my palm centro.

I was having the same problem. I finalyl have it working. With the boom closed on the headset Hold down the call button until the light turns purple immediatly let go of the button and then flip open the boom the light should remain purple. Then have the palm centro look for devices and it should now come up. Before I could not get it to locate any devices but now it reognized an "unnamed device" and then it does change it to the H700 after this you can connect it will ask for a passkey or password and it is "0000" Mine has been working fine now. Hope this helps all!!
