I have an old Pioneer speaker with an Apple 30-pin docking station. Unfortunately it didn't work with this speaker (model XW-NAC1-K) but it already has Bluetooth so it's not a problem. I also have an old Belkin dock with a speaker jack to connect to my stereo and it worked great. Very easy to use even without instructions. When you plug in the adapter, it will flash blue and red until you pair your Bluetooth device, then it will turn blue and you're connected. I'm only deducting a star for partial compatibility. I received this unit to test compatibility with the 30 pin docking stations I have at home.
