Having purchased a CMT-SX7B in December I have had no luck connecting it to a SRS-ZR7 to create a multi-room configuration! so i contacted Sony Support and had a reply from Rania who informed me that the CMT-SX7B is not multi-room compatible, this is despite the that John Lewis whom i purchased from saying it does, instructions to set it up are included with the product, and Sony website said it was in December. all very confusing and disappointing.
