you don't want the bluetooth settings on the BB turned on.
go to options on your Blackberry and click on Bluetooth make sure your bluetooth is in discovery mode the light should be blinking and have the BB search for it.
Once it finds it the Blackberry will have the name of the bluetooth pop up and ask to pair click on it. once it is paired it will ask if you want it to connect and click yes. If you can't get it to pair it may not be a good bluetooth for your BB I know when I had the BB my Motorola bluetooth didn't want to stay connected. I have the jawbone icon and have no issues with any device I use with it. Hope this helps you .
