Help with my BlackBerry HS-500 Bluetooth

Happy Holidays to All,
Over this last weekend, I purchased the BlackBerry HS-500 Bluetooth Headset for my Blackberry Curve 8530 powered by Sprint. It is a very nice device but I have one question about it.

How can I get my contacts' assigned ringers to play through HS-500 when they call me?

The generic ringer tone does not work for me if I am screening my calls while driving. I know that when I had my Motorola Razor phone and the Motorola Bluetooth Headset my contacts' assigned ringers would play thru the motorola bluetooth which may it extremely easy to screen my calls while NOT having to look at my phone or to have the phone on audible every single time.

Can anyone help with this?

Happy Holidays,
Ray...:confused:
