antenna issues after new headunit install
antenna issues after new headunit install I have a 2000 Trans Am, and have it has a motorized antenna. I used to have an Alpine flip-out unit and my antenna worked as it should. Whenever the source was on "Radio" the antenna would come up, and whenever the source was changed to "CD" the antenna would go down.
I recently installed a new Pioneer flip-out unit. For some reason the power antenna always stays up. Even when the source is not on "Radio", the antenna stays up.
Why is this happening? And what's the solution?

That is just the difference between different manufacturers head unit design. Some makers move the antenna up and down depending on music source (Alpine) while others just move it up and down based on whether the HU is on (Pioneer, GM OEM).

I had to do the opposite of this with my head unit install...
Try splicing your antenna wire from the head unit to the antenna wire to the car and splice the amp output wire to the accessory wire of the car if you have a factory amp or aftermarket amp...

BTW, the factory amp doesn't use a remote turn-on wire.

Ya I've got a Pioneer, with no power antenna wire from the HU. My antenna always stays down. I kinda want to switch it, but the radio still works (to the 90% margin) so I don't mind much. Thought about adding a wire to the harness for it, but no big deal. 3rd Pioneer and loved them all, Alpine sounds tempting for this, but why turn on a good thing? lol

Oh yeah? I think otherwise! I just had the biggest headache the other day trying to figure it out. Called up a local audio installer and he said wire it up like i told OP to do, as the Bose factory system wouldnt emit sound... worked fine once I did it.
The head unit antenna output would turn on the amp, but when in CD, AUX or Bluetooth it wouldnt emit sound but you can see it working... weird.

There's lots more information in the Monsoon FAQ sticky at the top of the section.
Antenna question if you dont mind.
My antenna goes up and buzzes/grinds. Its always up regardless of CD or fm radio. goes down with the powers off ofcourse. But the kicker is i have a factory radio and everything :/ My brothers TA does the right thing, cd down, fm up... why not mine??

Your brother must have an aftermarket head unit. The factory head unit puts the antenna up whenever it has power regardless of the music source in use.
Hmm. i thought his always did that :/ lol he has an alpine in it now, but i guess that solves that question..
One more for ya. any way of getting rid of the buzz/grind sound? ive read a few threads, but cant seem for anyone to have the same problem with a remedy. It only "grinds" at full extend.

Resurrecting an old thread. I have an alpine head unit installed and my power antenna never comes up even when I switch it to radio. Makes listening to the radio a pain because all of the static.

Can't tell without you doing some diagnostics:
- is the antenna getting constant (battery) power on the orange wire? If not, check the RADIO ACCY fuse first and then start tracing from there.
- is the antenna getting switched power on the pink wire when the radio is on? If not, check settings in the Alpine menus, check that the blue (or blue/white) wire from the head unit is properly connected to the blue wire in the wiring adapter harness (you did use an adapter harness right? - if not, the blue HU wire goes to the pink factory wire)
- if power is okay, are you sure the antenna even works? It could just be a dead power antenna.
