Bluetooth problem
 

I have a 2007 Camry. I have been able to pair my cell phone, make additions to the phone book, make a call and receive a call - all through the bluetooth system. However, when I turn the car back off and on again, I can't do anything through the bluetooth system. It tells me that my phone is unlinked. The only way I can make a call is to pair the phone again, and then all is well. But, when I turn the car off and on again...well, you see the problem...
