Q: Whats included in the box with the Garmin G5 experimental? Is it the instrument only? Do I need to order the installation kit and a harness? Battery extra as well?
Part # 11-14312 is the G5 instrument and User Manual only. Part # 11-14315 includes a 5 foot standard harness as well. If you order the unit only version, you will need to order the install kit separately. If you order the unit + harness version, the install kit is included. The backup battery must be ordered separately regardless of whether you order the harness or not.
Q: I intend to use the G5 in my glider (high performance sailplane). What is the current draw at full screen brightness? We do carry LiFe 9Ah batteries these days but we also do long flights of over 8 hours.
In a 14v system, the G5 draws .25 amps maximum. In a 28v system, it draws .125 amps maximum.
Q: Is the heading at the top of the G5 the ground track from the GPS?
No, it is from the magnetometer when installed with a G3X system.
Q: I intend to use the G5 for experimental aircraft as a standalone device in my plane. Is the HSI page still usable when the device isnt connected to other Garmin devices/GPS? In other words, does the non-STCd version of the G5 have an internal database with all world airports loaded? If not, how do one enter/select a waypoint for HSI navigation?
The G5 does not have an airport database build inside. It can only display HSI info when connected to an approved GPS source.
Q: Can the barometric pressure setting on the Garmin G5 be configured in Hectopascals rather than inches?
Yes, when configuring the instrument, metric can be selected for barometric pressure which will display hPa.
Q: If for some reason the Garmin G5 lost the GPS signal, what would happen with the attitude information?
The G5 has pitot static ports that would provide the airspeed, altitude, and attitude information in the case of a lost GPS signal.
Q: I do not have a CAN bus installed in the airplane, can the Garmin G5 be hooked up to 12V and Ground without the CAN bus?
Yes, the CAN-bus is for a G3X system. If you are using the G5, as a standalone unit, then you do not need a CAN-bus.
Q: Can the experimental version of the Garmin G5 be switched from Attitude Indicator to Heading Indicator and vice-versa?
Yes. The HSI functions can be accessed from the PFD display.
Q: Will the Garmin G5 work effectively in an experimental helicopter?
Per Garmin: there has not been any helicopter vibration testing done on the G5 to work in helicopters.
Q: Can I connect a Garmin G5 experimental with a 796 GPS?
Yes, you can.
Q: I wish to use only one G5 used in attitude mode, connected to an autopilot and a GNS530. I already have two CDIs, so do not need a second G5 with HSI. Is this feasible/possible? Is there a heading bug when in the attitude indicator mode?
The non-certified unit will interface with an autopilot system. If no magnetometer is present the ai will show trk instead of hdg. A track or heading bug will be displayed while in autopilot mode.
Q: I am thinking about replacing the DG in my RV-4 with a Garmin G5 used in HSI mode. Will it interface wirelessly with my Garmin Aera 660?
No, the Garmin G5 has no wireless capabilities.
Q: Can the airspeed tape on the Garmin G5 be configured in kilometres per hour?
No, it cannot.
Q: Is the Garmin G5 compatible with the Trutrak Sorcerer autopilot?
No, it is not. The experimental Garmin G5 is only designed for the Garmin G3X autopilot system.
Q: Regarding the G5 EFIS for experimental aircraft: Can I choose between knots or MPH on the speed tape? Also, can the altitude be in metric units?
Yes, for the G5 you can select between these available units of measurement within the configuration page.
Q: Is the Garmin GA35 the only GPS antenna usable with the Garmin G5? Since the G5 is a WAAS antenna Im thinking that a less expensive GPS antenna would be adequate for simple the alignment functions of the G5 rather than the expensive GA35 antenna.
The G5 can receive GPS position information using the unit's internal antenna, however, the reception quality is dependent upon the installation. For best results, an external antenna is recommended, with the approved models being: Comant 2480-201, or the Garmin GA 26C, GA 35, GA 36, GA 56, or GA 57C. Any equivalent antenna that meets the specifications will work with the G5.

- G5 unit
- G5 Installation kit
- 4 foot power/ground
- 4 foot RS232 data line
Q: Two questions: 1 - Can the Garmin G5 AI & HSI be connected to a Garmin 496 for Course Information? 2 - Can the G5 AI & HSI be connected to a Garmin 496 for Auto Pilot Information? Now, for the HARD question: If so... HOW? Do I need the GAD 29B?
The G5 can be connected to a Garmin 496 for course information. To do this, you would need the power/data cable 11-02694 which breaks out the wires needed to connect to an external device and send the NMEA GPS data needed. In regards to autopilot, the Garmin 496 could provide this data but it would not be through the G5. It would need to be wired directly to your autopilot unit.
Q: Can the Garmin G5 EFIS for experimental aircraft be set up as an HSI.
Yes, this unit can be setup as an HSI.
Q: Can the Garmin G-5 display a flight plan from a GTN 650 (all legs with colored active leg) as the Aspen 1000 does?
No, the G5 cannot display all legs of a flight plan with a colored active leg.
Q: Can the Garmin G5 show TAS? Would need OAT temp probe or a knob to dial in OAT? Does it interface with a 430?
The G5 can be connected to a GNS 430W for gps data. The G5 manual does not refer or shows a pin out for an oat probe. PER THE G5 MANUAL, Under normal operating conditions, the G5 provides the following air data information: Indicated Airspeed (IAS), Barometric Altitude Vertical Speed.
Q: Can the Garmin G5 be connected to a Garmin Aera 500?
No, these two devices cannot be connected.
Q: When a G5 is paired with a 430W gps will the navigation mode (HSI) show both a glideslope and localizer? This would be for an experimental aircraft.
Per the G5 manual, the G5 can show both the glide slope and localizer when using the GAD 29.
Q: How does the experimental Garmin G5 differ from the certified G5(s)? Apart from certification are the differences apparent and substantial?
The certified G5 will come with complete with mounting bracket and connectors. The experimental G5 will require separate purchase.
The certified version will only display it's primary function, while the experimental allows to switch between top and bottom. The certified version is locked on it's primary function.
The experimental version is more versatile in the screens it allows you to access from a single unit. Of course, the experimental versions is also only for experimental aircraft.
Q: Can the Garmin G5 be connected to a Garmin 196?
No, there is no interface compatibility between the Garmin G5 and the 196 GPS.
Q: Will the Garman G5 directly drive auto pilot servos? Or is a Separate control had like the 305 necessary?
It will drive a GSA 28 servo (Garmin G3X servo) via the can-bus input/output on the G5.
Q: Will the G5 interface with an non-WAAS GNS430?
Yes, the G5 will interface with both WAAS and non-WAAS GNS units.
Q: Can a 3rd Garmin G5 be added for the copilot position and be hooked into the other ones can bus?
No, there is only two unit IDs so a 3rd would need it's own connection to the pitot static system.
Q: You state below that a magnetometer cannot be used with two G5 units as primary EFIS. However the documentations seems to show that. It appears on G5 can be used as its primary function attitude indication and related and another can be used as a HSI/DG with a magnetometer, without a G3X! Please clarify this?
The GMU 11 can be used with two G5 units, so long as the G5's are tied together via the can-bus.
The only case in which a G5 can't have a magnetometer without a G3X is if you're using a GMU 22, which requires an interface from the GSU 25.
Q: Can Aircraft Spruce make up a custom harness for two G5s and a magnetometer with owner defined lengths? Basically two G5s together side by side, fed from two 5 amp CBs, and a owner defined length with no termination on it for the magnetometer. This would be to allow owner to pull harness through necessary fuselage and wing struts to get to location for magnetometer.
Yes, please contact our Avionics sales department and our team can build a custom harness with desired lengths and terminations.
Q: Can the internal GPS in the Garmin G5 be used as a WAAS GPS source for ADS-B out?
The internal GPS on the Garmin G5 is not WAAS and cannot be used as a WAAS GPS source.

It can but we do not see any value in doing this as the G5 cannot provide any AHRS info to the 696.
Q: The installation manual states, One installation kit (011-03892-00) is required to install each G5 unit. The installation kit is not included with the G5. Do you sell the installation kit?
See part # 11-14313 for the G5 install kit.
Q: Are there functional differences between the Garmin G5 certified and non certified versions?
They are the same physical unit but the software is different and thus there are a few differences between the units.
The G5 experimental can do both attitude and dg/hsi screens where the certified unit can only display one screen per unit.
Q: Can two Garmin Autopilot servos be connected to the G5 for both pitch and bank or does it require the G3X head to enable 2 axis autopilot functionality?
If you are running a stand alone system, then you will need the control head for the autopilot system. all of the units will be interconnected via the can-bus for control and display.
Q: Do you offer a pre wired harness for garmin g5 experimental?
Yes, if you order Part# 11-14315, we will ship the unit with the prewired 4 foot harness.
Q: May I send to the G5 VOR/ILS signals from any NAV equipment (Bendix/King, Narco, etc) or it must be a Garmin NAV like the SL30 only?
No, the older King and Narco products will not work with the G5 as they need a arinc 429 input and output.
Q: How/where is VSI displayed on the Garmin G5 experimental, and is it GPS or altimeter based?
The VSI is based on the static port input on the back of the G5 and is displayed on the side of the altimeter tape.
Q: Is it mandatory to order GARMIN GMU 11 MAGNETOMETER FOR G3X & G5 to use the Garmin G5 or is it working without ? It seems to be not provided in th G5 kit.
