The map and data can be seperated, onto seperate monitors, but the display is expected with future software versions to suffer a 5 minute delay.
The idea is to use an external program, such as SBS viewer for the map.
RB will currently NOT do this directly!!! It was requested a while ago, but I am not sure if AirNav Development are looking at it, as an update in the next version.
The delay is due to SBS viewer using the output on Port 3003, and ALL port traffic is due to have the delay re-implemented in future versions.
