+# The Sony car stereo Ford is using under their brand as '6000 CD' has a
+# completely broken AVRCP 1.3 implementation. After recognizing AVRCP 1.3 TG
+# capabilities and exchanging a few PDUs, the car stereo disconnects and
+# reconnects BT, also resetting USB devices if connected to it.
+# To avoid that and allow at least HFP and A2DP to work, prevent any AVRCP 1.3
+# PDUs from being sent on those models - add the device to the black list.
+# Since 2012 Ford models have it fixed, removing the device from the list
+# will result in full functionality.
