No. The BT transmission can cause interference with the electronics that are used on the aircraft. In my own experience, this is usually manifested in interference heard over the communications and navigation radios.
There are a number of navigation systems on the aircraft that are analog, including the instrument landing systems, and they do not have the capability of ignoring any signal that is causing interference.
