Summary: i was disappointed when hearing the sound after installation. later, I found the format of the SD card was different, which means I could not move my mp3 files from my computer to the SD card and play them back with the machine. even worse, my computer could not recognize the format of the SD format unless I used the unfriendly software of panasonic.
Summary: We were looking for a system to hook up so music could be sent to all rooms in our home-this system is excellent-we download our cd's on the mp3 player then insert the SD card which holds 1 gigabyte and we can just play music forever. I would highly recommend this system-great buy for the money. The hook-up and operation of this system is simple so anyone could use it.
