First thing you have to do is pair the two devices. Then go to your head unit and go to the function screen for BT and go to transfer contacts. Next on your BB go to manage connection and select Bluetooth options. Under paired devices highlight the Pioneer BT unit and hit the menu key and go to "device properties". Once you are there scroll down to where you see "services". Hit the menu key and go to "Refresh Service List". It will take a moment when its done it should say "Object Push" under services now. Now you can go to the menu key and go to "transfer contacts".
