Best Answer

When your head unit is turned on, the auto-antenna wire sends a signal to your automatic antenna (meaning moves up and down as your HU turns on and off respectively) which moves it up or down.

It works in the same way as the Remote Amp Turn-On wire works, which turns your amp on with you HU, then off when you turn your HU off also.

Both are usually coloured blue, or blue and white on aftermarket stereo systems.

How do you get the antenna to go up with a new stereo installed if the antenna wire is connected to the stereo but the antenna won't raise now even from the switch?

The motor that raises and lowers the antenna is controlled by a wire which is connected to the power switch in the stock radio. The wire from the antenna itself has nothing to do with raising and lowering the antenna. Touch the wires that were connected to the stock radio to a hot wire and see if the antenna starts to move. If if does, hook that wire to the wire from the new radio which is supposed to control the antenna motor. If there is no such wire, connect the antenna motor wire to the Accessory circut. The antenna will go up whenever the key is turned on. Or, you can get fancy and install a switch for it.
