Default Power consumption of GNX 375 and GPS 175?

Can anybody point me to the current draw (continuous and peak) for the GNX 375 and GPS 175?

Thanks

Hello Raiz,

GPS 175 GPS Navigator
14V: Typical 0.6A, Maximum 0.9A
28V: Typical 0.3A, Maximum 0.6A

GNC 355 GPS Navigator with COM radio
GPS/Main Connector
14V: Typical 0.6A, Maximum 0.9A
28V: Typical 0.3A, Maximum 0.6A
COM Connector
14V: Typical 1.8A, Maximum 6.0A
28V: Typical 0.9A, Maximum 2.8A

GNX 375 GPS Navigator with ADS-B In/Out 250W 1090ES Transponder
14V: Typical 1.2A, Maximum 1.8A
28V: Typical 0.6A, Maximum 0.9A

The low power consumption (compared to older equipment) is another reason these units are attractive.

Thanks,
Steve

I'm part way through a complete panel update and thinking about swapping the GTX 45R I have for a GNX 375. My setup is:

GDU 460
GDU 470
G5
GSU 25
GMU 11
GPS 20A
GEA 24
GTR 20R
GTX 45R

I know I will need to panel mount the GNX 375. What other equipment needs to be changed? Do I still need the GPS 20A? Do I need a GAD29?

Yes you need the GAD29 and you can ditch the GPS20A.

Default GNX375 and G5

Pulled the trigger on a dealer install GNX375 coupled to a G5.

I will update and review the experience and process along with capabilities in case anyone else wants to wander down this road once the new avionics are installed and flown.
Seems like a great upgrade for a steam gauge older transponder/gps without ADBS-out.

I'm planning to have a dealer install of a 375 with a G3X shortly after Oshkosh. Very excited.
