question on head unit installation. Options

[Zimluura]

hey, i recently got a new pioneer premier DEH-P680MP head unit and i really like it.

when i was hooking it up there wasn't a blue cable to go to the antenna. so i left that hanging. but now my antenna doesn't go up when i switch it to radio. so anyways, i'm now noticing that the installation instructions say something about the blue & white wire that had a little remote label on it.

they say: "To system control terminal of the power amp or Auto-antenna relay control terminal (max. 300mA 12V DC)"

so i'm thinking maybe i want to hook that up to the blue antenna cable.
does this sound like a good idea? or does this sound like a really really dumb thing to do?

thanks in advance

i think the Blue wire (remote) is for sending the signal to an amplifier when you are running subs. When installed a 12' sub for my friend, it would not work until i hooked up that blue wire to the remote terminal on the amplifier. So... my vote is that is not the antenna. I think it was more like a black plug thats separate from the wire harness. not 100% sure though.
