This gauge is a readout for FS2000/FS2002 and FS2004 GPS. It displays the current navigation data from the built-in FS GPS and provides GPS map display switching and GPS/NAV switching. The data formats displayed are based on the ones provided by the Bendix/King KLN 90B GPS. This gauge does not simulate a GPS, it only provides display and switching functions.

GPS is provided by: Ike H Slack of Coyote Avionics Design
This gauge displays the data needed to navigate and fly using the built-in GPS in a realistic display without having to use the built-in GPS display except when changing GPS modes.

The D-> button toggles the GPS display on and off and the ENT button replaces the GPS/NAV switch normally used when using the GPS to drive the autopilot. When the GPS is the NAV source "GPS" is indicated in the lower right corner of the display.

The display contains eight lines of data with the upper right line displaying three XTK modes and two CDI scales when in the CDI mode.
