Old da-ns410 speaker. Trying to connect.

[DaveCantin]

Hi - After many years I have taken my day-ns410 speaker out of a box and tried to get it working from my iPhone SE (os 14). 
Was running the speaker a few years ago through a jack plug on old phone. New phone doesn’t have a jack. 
Tried finding NS Setup on App Store but looks defunct. Would love to get this speaker working wirelessly again.

At home you can try by connecting it to your home network, it is AirPlay compatible ...
