Should have posted this earlier, a few months ago I installed ADS-B in and out in my 650. Got the UAT and Wifi setup from SkyVision. Connects to my ipad. At a glance its easy to see if a plane is above or below you, and which way it's going. 3-D view. Harry the tec at SkyVision is the most helpful and quick reply with help and answers. So far a few planes are using ADS-B. But more and more. Love it.
