Pioneer in car stereo wont work?

Hi i need some help with a Pioneer DEH-3350UB Car Stereo with CD MP3 USB Tuner iPod Aux?

• hi my sister has a Pioneer DEH-3350UB Car Stereo and when she puts the radio on in the car the electric antenna wont go up and i have checked all the wires on the stereos wiring harness and there is only one remote turn on wire what is being used for her rear speakers amplifier + subwoofer amplifier is there any way i could get the antenna going up when she puts the radio on and for it to go down when she listens to a cd or her usb stick? i am thinking of putting a small switch in the dash and wire it up to the remote turn on wire and connecting the wire for the power antenna to the other side of the switch will that work ok?

• Answer:

  at the back of your headeck, you will have a (blue or light blue) cable which is your antenna wire. your car will also have a wire, which when connected will make your antenna go up and down when powered on.
