How do I make the power antenna go up when the radio turns on after installing a new aftermarket headunit?

It appears to be that the radio clock display has malfunctioned, and is due for a replacement radio, which could be an aftermarket or oem radio, maybe found at a junk yard.

Tools required for oem replacement radio, torx keys set.

Before working on the radio or other electronics, disconnect the battery cables with 8mm wrench.

Replacing the oem radio is much easier, if you obtain oem radio, compared to aftermarket radio, due to being direct fit.

The radio is same for 1995 to 1999 Pontiac Sunfire and the Chevy Cavalier, regardless of sub models, such as SE,GT, VL,VLX,Z24. etc.

Parts needed for the the aftermarket radio install :Stereo assembly, stereo wiring harness adapter, radio antenna adapter, and dash install kit.wiring diagram for the wire colors / functions, along with tools, such as torx key set, screwdrivers,wire crimper, wire stripper, double ended wiring connectors, hair dryer.

The oem stereo removal video is for the 2000 to 2005 Sunfire / Cavalier, but are the same or very similar procedures.

Have a nice day.

It is the top[ lines in the rear glass. If you look close, you can see the separation. Most new window tints are metallic, and ruin the antenna, I made sure they didn't tint the antenna on my 2003 Civic. Any aftermarket antenna will work, the antenna cable coming out of the radio is just like any other.

the cable that plugs in for the aerial could be a extension piece and puilling the old radio out could have unplugged this extension?

Yes, It's a very good possibility that you will have a few wires left over. Normally a wire for an aftermarket amp to be triggered on when you turn your radio on and possibly a power antenna or a dimming function that dims your radio lights when your headlights are on. It of course always depends on if you have a power antenna or not, or if you have an aftermarket amp or not or if you have the dimming feature on your car or not. These wires don't apply to everyone.
You will just match the colors between the wiring harness that came with the DUAL radio and the interface adapter that goes to your car. Make sure you use **** style crimp connectors. If not the wires could come loose or cause a popping noise or cause the radio to turn off while driving.
Other than that, installing an aftermarket radio is mostly matching the colors up between the two harnesses and crimping the wires together.

following is the procedure. u can also check ehow for more details.

Twist the negative cable off the terminal on the vehicle battery, using an adjustable wrench.

Remove the factory issue stereo. Pry off the radio trim bezel with a flat head screwdriver. Remove the four bolts on each corner of the radio. Pull the radio out the dashboard. Unplug the thick black radio antenna cable. Disconnect the wire harnesses from the rear of the stereo. Place the old stereo to one side.

Prepare the dashboard for the new stereo. Fit the radio installation sleeve provided with the aftermarket stereo to the radio installation kit. Feed the sleeve through the portal of the radio installation kit and bend the tabs on the sides of the sleeve to secure it in place. Feed the audio wiring of the Jeep and the radio antenna cable through the portal of the assembly and slide the assembly into the dashboard. Secure it in place with the bolts removed earlier.

Wire the new stereo. Connect the wiring of the stereo to the audio wiring of the Patriot, using a custom wire harness adapter. Push the connections together until they snap into place and test the connection by tugging gently on either end.

Plug the radio antenna cable into the alloted port on the rear of the aftermarket head unit.

Slide the connected aftermarket stereo into the prepared housing in the Patriot's dashboard. Click it into place in the radio installation sleeve, taking care not to trap any wiring.

Hope this helps (remember to rate this).

Most aftermarket pioneer cd/radio decks have the electrical connector for the antenna that I've seen.

Is this a cd only deck, or does it have radio functions?

Did you use a new harness wiring adapter to get the pioneer radio to work with the old harness?
There should be a color coded set of wires for the power antenna on that. And, then the Pioneer radio should have wires that were labeled for the power antenna.

this is normal the power antenna gets power from the radio and unless the radio is shut off either from powering it down or turning off the car it will stay up. if it is an aftermarket stereo and is staying up when you are on cd's check to make sure that your antenna is hooked to the antenna output on the radio and not the system remote as the system remote is hot any time the radio is powered to run amplifiers.

You have to unplug the old radio. The radio isn't the part in the dash. That is just the control to the radio. The radio is actually under the dash above the accelerator pedal. It should have the power wires, speaker wires and antenna wire going to it.
