I’m getting ready to add a second display myself. As well as radar. Curious to hear everyone’s response. I have a two year old ray marine A series. We can blue tooth to a tablet but it’s not the easiest thing to do. Plus it is only a viewer. And you can’t switch views drop a pin or change direction on the auto pilot. A new ray marine display that is compatible is over $2,000 and the A series is no longer available. My installer is looking for a used unit for us...
