Hi, all posting again as I put this in the wrong forum and have also found some of the information I needed.

I have aquired a set of DSP5200SL and I also have a 218 that I plan to use but it's on a very early firmware version and I would like to get the update to work with Sonos. I have trawled the forum and can see that it looks like public access to the update manager have been pulled, new links added but these have all been broken. Can anyone direct me to somewhere i can get the update manager so that I can update the 218?

Many Thanks

DSP5200SL, 218, with Sonos. Rest of home Loxone multi room audio with Monitor Audio speakers
