I unzipped them on my PC, renamed them ( I didnīt like the numbers of them, e.g. "WALZER.SRG" ) with numbers that fit to my registrations and just copied them via USB-Connection to my Audya5īs "/Registration/Single" folder.
Unplugged the Audya ( prior to that donīt forget to use "Disconnect Hardware" from the PC !!! ) and could use them.
