Which Terrain Resolution to Download for G1000
The Terrain resolution used on a G1000® flight deck is based on the Garmin Display Unit (GDU™) avionics version that the system is running.
- To check the GDU software version on your G1000:
- On the Multi Function Display (MFD) navigate to the AUX - System Status page.
- Press the LRU soft key.
- Scroll down through the LRU list to find the MFD1 listing.
- The software version listed on the MFD1 line with the column heading labeled Version shows the MFD software installed in your unit.
- Compare your GDU software version with the list below to find the correct terrain resolution:
- Less than 9.00: Worldwide 30 arc/sec.
- Between 9.00 and 14.99: Worldwide 9 arc/sec.
- Equal to or greater than 15.00: Worldwide 4.9 arc/sec.
- Note: If you fly a helicopter equipped with a G1000H, you can download the regionalized high-resolution Terrain database if your GDU software version is under 14.99. However, if your GDU software version is 15.00 or higher, you must use Worldwide 4.9 arc/sec Terrain.
