If you don't want to buy a new phone just to get the bluetooth working in your Toyota Prias and you are using a Palm 650 Treo cell phone, here is what you can do to sync them:

1- Turn on the bluetooth on your phone.
2- On the prias, go to the bluetooth settings and set the password to 0000.
3- Begin the process on the car to connect to devices.
4- on the Palm, go into bluetooth again and begin the handsfree device wizzard.
5- You will see the Prias show...
