If you have purchased a receiver for your Bose dock, which doesn’t power up, it is the incorrect device for your dock. The BS-1 has been uniquely designed to work for the Bose Series 1 SoundDock. It will only work with this dock and will not work with later models.
If you have an old Bose Docking station and are trying to work out which Bluetooth receiver you need to buy - please read this post before purchasing. Even if you are sure you have a Bose Series 1, there are actually two generations of the Bose 1; both of which work off a different charge output and both require a different receiver.
