The Blackberry platform
Before pairing your Blackberry® phone with SYNC:
Turn Bluetooth On
Under Bluetooth Options, set Discoverable to Yes, set Connect on Power Up to Yes
If available, under General Options, set Default Call Volume to Previous
During pairing, when asked, set Allow Outgoing Calls to Always. You may need to first check "Don't show me this message again."
After pairing, under Bluetooth Device Properties, set Trusted to Yes.
In rare cases, you may have trouble pairing your Blackberry with SYNC, or no sound comes out, or your Blackberry is frozen in “thinking” mode when you try to use it with SYNC. To solve these issues, try rebooting the device: remove the phone’s battery, wait 30 seconds, then reinsert it.
