Samson’s BT30 30-Pin Bluetooth Adapter transforms Apple 30-pin dock audio players, including select Samson Expedition Series Portable PAs, into Bluetooth-enabled receivers capable of streaming music wirelessly from smart phones, tablets and laptops. Ultra-convenient and easy-to-use, the BT30 lets you enjoy the latest in audio playback technology without sacrificing the useful accessories you’ve grown accustomed to for playing music, such as older iHomes, PA systems and more.

Not a bad idea. I have a few of these older speaker docking stations myself.
