Hello @twangy57 , you need to download the Auralic Lightening Control App, on an iphone or ipad.

I believe you can also set up the Vega and play from it using the front control and buttons, but it is MUCH easier using Lightening on an ipad. What model of Vega???
For my eyes, an ipad is the way to go, and if you don't have one, a basic one is not that much.
The Lightening App walks you through finding, connecting and using the Vega.
