I have a Motorola Q Music 9M (WM6.0) from Verizon and while I have no problem getting the phone to pair with sync, shortly after pairing the phone disconnects.  Also, many times the phone will not respond to the sync system.  I frequently get "Phone Disconnected".  I've re-paired several times and get the same problems.  The phone works flawlessly with other Bluetooth devices and Sync works fine with my wife's Razor.  So I can only conclude it is a compatibility problem.  I've looked for updates on both devices but there are none.  I assumed since the Motorola Q (WM5.0) was on the compatibility list that the later version running WM6.0 would have no problems. 
  
Anyone else out there with the same equipment having similar problems?
