FREQUENCY SPACING
The	G1000	 COM	radios	 can	tune	 either	 25-kHz	 spacing	(118.000	 to	136.975	 MHz)	or	8.33-kHz	 spacing	
(118.000	to	136.990	MHz)	for	760-channel	or	3040-channel	configuration.		When	8.33-kHz	channel	spacing	
is	selected,	 all	of	the	 25-kHz	 channel	 spacing	frequencies	 are	also	 available	 in	the	 complete	 3040-channel	 list.			
Variable	rate	tuning	is	provided	with	8.33-kHz	spacing	to	achieve	faster	selection	of	the	decimal	digits.
COM channel spacing is set on the System Setup Page of the AUX Page Group.

AUTOMATIC SQUELCH
Automatic Squelch quiets unwanted static noise when no audio signal is received, while still providing good 
sensitivity to weak COM signals.  To disable Automatic Squelch, press the VOL/SQ Knob.  When Automatic 
Squelch is disabled, COM audio reception is always on.  Continuous static noise is heard over the headsets and 
speaker, if selected.  Pressing the VOL/SQ Knob again enables Automatic Squelch.
When	Automatic	Squelch	is	disabled,	a	white	SQ	appears	next	to	the	COM	frequency.

4.3 NAV OPERATION
NAV RADIO SELECTION AND ACTIVATION
The	 NAV	 Frequency	 Box	is	composed	 of	four	 fields;	 two	standby	 fields	and	two	active	 fields.	 	 The	active 
frequencies are on the right side and the standby frequencies are on the left.
A	NAV	 radio	 is	selected	 for	navigation	 by	pressing	 the	CDI	Softkey	 located	on	the	 PFD.	 	 The	active	 NAV	
frequency selected for navigation is displayed in green.  Pressing the CDI	Softkey	 once	selects	 NAV1	as	the	
navigation radio.  Pressing the CDI	Softkey	 a	second	 time	selects	 NAV2	as	the	 navigation	 radio.		Pressing	 the	
CDI Softkey a third time activates GPS mode.  Pressing the CDI	Softkey	again	cycles	back	to	NAV1.
While cycling through the CDI	Softkey	 selections,	 the	NAV	 Tuning	 Box	and	the	Frequency	 Transfer	Arrow	are	
placed	in	the	active	NAV	Frequency	Field	and	the	active	NAV	frequency	color	changes	to	green.
The three navigation modes that can be cycled through are:
•	 VOR1	 (or	LOC1)	 –	If	 NAV1	 is	selected,	 a	green single line arrow (not shown) labeled either VOR1	or	LOC1	
is	displayed	on	the	HSI	and	the	active	NAV1	frequency	is	displayed	in	green.
•	 VOR2	 (or	LOC2)	 –	If	 NAV2	 is	selected,	 a	green double line arrow (shown) labeled either VOR2	or	LOC2	 is	
displayed	on	the	HSI	and	the	active	NAV2	frequency	is	displayed	in	green.
•	 GPS	 –	If	 GPS	 Mode	 is	selected,	 a	magenta	single	line	arrow	 (not	shown)	 appears	 on	the	 HSI	 and	neither	 NAV	
radio	is	selected.		Both	active	NAV	frequencies	are	then	displayed	in	white.

AUTO-TUNING A NAV FREQUENCY FROM THE MFD
NAV	frequencies	can	be	selected	and	loaded	from	the	following	MFD	pages:
•	 WPT
The	MFD	 provides	 auto-tuning	 of	NAV	 frequencies	 from	waypoint	 and	nearest	 pages.	 	 During	enroute	
navigation,	 the	NAV	 frequency	 is	entered	 automatically	 into	the	NAV	 standby	 frequency	 field.		During	 approach	
activation	the	NAV	frequency	is	entered	automatically	into	the	NAV	active	frequency	field.
Frequencies	can	be	automatically	loaded	into	the	NAV	Frequency	Box	from	pages	in	the	NRST	or	WPT	page	
group by highlighting the frequency and pressing the ENT	Key	(Figures	4-23,	4-24,	and	4-25).
Auto-tuning a NAV frequency from the WPT and NRST Pages:
1) From any page that the NAV frequency can be auto-tuned, activate the cursor by pressing the FMS Knob on the 
MFD control unit or selecting the appropriate softkey.
2) Turn the FMS Knob to place the cursor on the desired NAV identifier or NAV frequency.
3) On the Nearest VOR, Nearest Airspaces, and Nearest Airports pages, select the FREQ Softkey to place the cursor 
on the NAV frequency (Figure 4-25).
4) Press the ENT Key to load the NAV frequency into the standby field of the selected NAV radio.
5) Press the Frequency Transfer Key to transfer the frequency to the NAV Active Frequency Field.
Press the ENT Key to Load a 
Highlighted Frequency into the  NAV Standby Frequency Box.
