If you have a Toyota Camry, and you want to delete the phone from the car’s Bluetooth system, there are a few steps you can take. First, open the car’s door and remove the battery. Then remove any obstructions from the way of the phone’s connection to the car’s Bluetooth system. Finally, plug in the phone and reattach the battery. If all of these steps don’t work, or if your phone still isn’t deleting its data after trying them, then it may be because there is something blocking your Bluetooth connection. Try unplugging and reconnecting your device several times; if that doesn’t help then you may need to call Toyota customer service.
