I have a 2004 TL.

Recently the car has encountered some electronic gremlins. The latest is that the audio system in the car is not producing any sound (though voice recognition is operating as normal). Also not producing any sound output is the Bluetooth system; indeed pairing procedures are not working and not recognizing the phone. I know the Bluetooth system can listen to my voice input though, as it displays the bluetooth password I select when I say it.

The display above the navigation system simply reads, "CODE"
I have tried disconnecting and reconnecting the battery (waiting 3-4 min as an interval), and have entered the PIN code for the navigation system.

Anyone had a similar experience, and hopefully a fix?

Thanks!
