Pandalet may shortly have a solution for Bose X users who want to integrate mobile phones via Bluetooth...
Another, and for some, a better, solution is in the works. PS Engineering, the audio opanel manufacturer, has recently announced the PMA 8000BT, an audio panel with integrated Blue Tooth capability. Said to be plug compatible with the PMA 8000B and Garmin GMA 340, both very popular audio panels.
