Do I need gtn650 Nav antenna for initial powerup?
Like the title says.
I'm getting close to first power up and the wings aren't on so no archer antenna or cable hooked up yet.
I know that you can blow out a transmitter if you don't have an antenna hooked up, but what about the nav half of the GTN650?
I think the answer is no, since it's obviously receive only, But so far I haven't had any luck finding a answer in Garmin's zillion page manual.
Can anyone answer this question definitively?
