Sounds like we had the same problem. The X3 has an issue durring heavy rain that cause water to enter into the compartment where the Bluetooth/voice/handsfree function is located. All of the electronic for these funtions are housed in a metal box that is about the size of a brick, but with only half the thickness. Over time the moisture cause some internal corrosion which ultimately causes the unit to fail completely. Oh, and did I mention that it is very expensive to replace this magic box? Last time I checked it was $1700 new and the used units that I found were still going for well over $900
