The Belkin Bluetooth Music Receiver is particularly well suited to music on the stereo system to transfer. Only a socket for the current supply should be placed in the vicinity. I use the device to my iPhone. I've noticed that it takes almost a line of sight, so no interruptions occur.
When the two, however, 'without moving between' distributed close enough in space, but there should be no problems.
Conclusion: for the price you get a chance its must sees on older 'often still high' stereos enjoy.
