Hmmm. Somehow I thought that the Bluetooth update was different than that system update. I am running v2.003 and my bluetooth connection stinks ever since I upgraded my iPhone to IOS5. In this link for the map update, it lists a Bluetooth firmware update. Is that the same as the system update noted above?
