Does anyone know of a product that will allow me to wirelessly connect to a Receiver. I want to be able to play music from my iphone (itunes, pandora, ect.) on my office audio system without having to put my phone actually into a dock. I use my iphone as a reference source to look up drugs and to keep track of emails. I can not place it on a stationary dock. However, I also want to be able to play my music from it. I know that Sonos works very well, but I already have hardwired speakers in all the rooms that I will want the music to be played in and they all go back to a central amplifier. Any suggestions?
