I'm working on an MI-171 Helicopter, with an IN 182A Color Weather Radar Indicator (Honeywell Bendix King) installed on it. Part No of IN 182A is 066-3084-32 (It says "graphics compatibility for display of navigation information" with this model). Currently the indicator is not showing any navigation graphical information or moving map display. It only displays a weather radar picture. The bird also has got KLX-135 installed onboard.
Now the problem is, how to incorporate navigation information with moving map on IN 182A along with Weather Radar display as well. The LRU has got MAP and NAV buttons, but they do not function.
Help required.
Thanks.
