Help please - Replacing a ReadyNas Duo V1

Hi. Have an old ReadyNas Duo V1 (RND2000) which has finally failed (Drives are OK but unit not accessible on LAN and will not power down). Have been thinking of upgrading to a later model anyway so now have to. Have used current unit with LMS add-on to stream music to Logitech Radios and Squeezebox Duet. Could someone confirm that the LMS Add-on is OK to use with the Netgear ReadyNas 100/200 products and that I can still use with Radios/Duet?

Thanks
