Just for info my tuner didn't show up at all first time the empeg booted up, that's when I noticed I now had no sound at all even playing files. Turns out my amp. remote wire had pulled out of docking connector ( possibly my fault), while trying to connect tuner. I fixed (soldered) wire myself, pushed player into sled & everything worked & tuner was present. So I'm not sure if it was a connection originally as to why the tuner didn't show up at first or because it was rebooted a couple of times.
