I noticed that the wiring for a power antenna is already in place inside my trunk. Can I install one and have it work, or are there connections to be done at the stereo?

I think Jr just went through this. Successfully, I might add. You also need to make sure you have the purple (I think) wire on the stereo. That'* the one that raises and lowers the antenna. I'd check for a 12v signal as you power up and power down the radio.

My power antenna finally took a crap this weekend. Time for a new mast. Just glad I noticed it running and not going down before it ran my battery to nothing.

Excellent. I think I'll grab one tomorrow and give it a try.
