I just bought a 2012 Camry SE and noticed the Bluetooth option would not turn on so I could pair anything. I had a friend of mine who is a Toyota Master Tech do an update for me, but in the first phase of the update it says that it is unable to start the ETFS drivers. Now there is a constant message that says it is in update mode and to insert a valid USB stick. I am unable to use the backup camera, navigation, or change the source for the stereo. Nothing but the FM radio works. Any help would be much appreciated.
