i had much problems with my Treo 680....so many in fact that I sold it and went with a Cingulair 8525. Now bluetooth works perfectly! You're only solution maybe to upgrade to the latest bluetooth module (see bimmernav) AND/OR go up to your cellular provider and have them test EVERY phone with your X5 to see which one pairs and transfers the best and then choose that one. That's what I ended up doing after I updgraded the BT module to the latest Visteon module. Now it loads and downloads and connects flawlessly.
