Pages: Use outer knob to cycle through MAP, NAV, WPT, AUX, NRST pages.

Setup Menu: Configure system (units, time, alerts), sensor calibration, interface settings (serial ports, ARINC), display (contrast, backlight). Navigation Settings: Select desired CDI sensitivity (enroute, terminal, approach), set barometric minimums. Alerts: Configure terrain, traffic, and airspace alerts.

Connecting Devices

Standard interfaces: ARINC 429, RS-232 serial. Typical connections: VHF COM radio, VOR/ILS receiver, Transponder, Audio Panel, Autopilot, Fuel Flow sensor.

  1. Ensure aircraft power is OFF.
  2. Connect appropriate interface cables to rear connector pins per installation manual.
  3. Configure each serial/ARINC port in the SETUP > INTERFACE menu for the connected device type.
  4. Verify data exchange on appropriate pages (e.g., COM frequency on NAV page).

Tip: Refer to the Garmin GNS 500 Installation Manual for detailed wiring and configuration.

Navigation & Flight Planning

Supports direct-to navigation and multi-leg flight plans.

  1. Direct-To: Press D-> key, enter identifier (airport, navaid, waypoint), press ENT.
  2. Flight Plan: Press FPL key to create/edit. Use inner knob to select legs, outer knob to scroll.
  3. Activate/Deactivate: Press MENU on FPL page to activate leg or entire flight plan.
  4. Nearest Airports: Press NRST key for list of nearest airports with relevant data.
  5. Approach Selection: From PROC key, select desired approach, transition, and activate.
  6. Hold: Define and execute holding patterns from PROC menu.
  7. Vertical Navigation (VNAV): Set altitude constraints for flight plan waypoints.

WARNING! Always cross-check GPS navigation with other available means. GPS signals may be unavailable or inaccurate.

Database Management

Navigation database is updated via Jeppesen data card.

  1. Power off unit.
  2. Insert new data card into front card slot.
  3. Power on unit. It will automatically recognize and load new database.
  4. Verify database effective date on AUX > STATUS page.

CAUTION! Do not remove data card while unit is powered on. Ensure database is current for intended flight operations.

Care & Cleaning

Turn aircraft power OFF before cleaning. Use a soft, lint-free cloth slightly dampened with water. Do not use solvents or abrasive cleaners.

CAUTION! Do not allow moisture to enter unit through seams or connectors. Keep display cover clean for optimal visibility.
