    Wireless room for 24i Junior (old, non-greenstar version)?

    Hi, I have one of these, which is older than the greenstar version. I believe it is called the RSF. I wanted to buy either of these two, but some posts I've seen elsewhere suggest that they may only work with the newer greenstar, not my RSF: Any advice appreciated, thank you, gbar
