Top glass panel maker Dynon just updated its SkyView panels to include air traffic alert and graphic display, just like the TCAS (Traffic Collision Avoidance System) the big boys have...although for many more Grover Clevelands.

Typical Dynon SkyView screen...TCAS symbols not yet available

Traffic targets will show up on SkyView’s moving maps and synthetic vision displays as standard TCAS I symbols, identify the location, severity of the threat, distance, vertical separation and heading of any aircraft within the traffic system range.
Nothing like having your own radar-like warning system in flight.
SkyView can also receive traffic information from a Zaon XRX PCAS passive traffic receiver, a Navworx ADS-B receiver, a Trig ADS-B receiver, or any device that outputs the industry standard
GTX 330 TIS traffic format.
Essentially this means SkyView’s new traffic feature can be used worldwide.
The new traffic feature comes with all Version 2.6 software, available now on all new SkyView units and downloadable for free for current SkyView owners.
