About to convert my pcm 3.0 (997.2) to an aftermarket stereo. But I am a bit confused. Which is the antenna connection ? there is a blue and a black similar output.
I think the blue is the antenna but what is the black one ? I have searched the web but no answer, am I stupid ?

 

i think the blue is nav

 

Ignorance is not knowing what the black one is. Smart is asking and researching. Stupid is plugging electrical things together when you don’t know what they are. So you’re not stupid. Yet.

ps: sorry I can’t help you but I usually just get stupid and plug em together and see what happens
