Does the Garmin GNS-530 contain interface capability for weather radar?
No. Currently, the GNS-530 does not support an interface for analog or digital weather radar display. Since the GNS-530 is intended to be a multifunction display containing such information as GPS, Nav, Ryan TCAD, and Echoflight , the potential is present. Although the possibility has been addressed by Garmin, they have not released any projected date or timeframe for this interface.
