Break the iMonopoly and use any bluetooth phone (Android, Blackberry, Windows) or device (iPad, computer) with any iPod dock. The Bluewave Bluetooth Audio Receiver connects directly to any 30-pin iPhone speaker accessory and pairs wirelessly with your Bluetooth device.
Not only can you now use non-Apple gadgets with iPhone speaker docks but you can now connect your iPhone (or iPad or iPod) to the speaker dock wirelessly. That means you can actually use your phone while it’s streaming music. This would also be a great solution for your car if you only have a USB jack for audio input but no Bluetooth. It opens up a whole world of speaker docks and accessories to Android users too. $39.99.
