Garmin Avionics Current Draw
 

I am laying out my electrical system and need the maximum current draw for a few Garmin products that I plan on installing. Can't find the installation manuals on Garmin's website.

GNS430
GTX327
GMA340

Can anyone help ?

Garmin Amp draw
 

Draw versus recommended breakers is two different things.

The 430 is a 10 amp breaker

Whoops
 

430 is 10 amps

I'll have to look up the others. I believe the 327 and 340 are 5 amps.

Steve,

For the Garmin products you are interested in the links below will get you the installation manuals. The first one is for the GPS 400 GNC 420 GNS 430 Series, and the others are self explanatory.

Michael Stewart posted a lengthy message on the RV list some time back on how to find the Installation and Pilot manuals etc. from the Garmin web site.
