A few hours ago I put a Sony Head unit in my friends car. Not sure what model; her parents took it out of their old car. Once it was wired up, we tested it. The tuner was coming in static-y or not at all, depending on how we moved the antenna wire around. It was a 2000 corolla and didn't require an antenna adapter. The cd function and aux function work fine and sounds clear. They listened to fm radio with the factory HU on the way here, with no problem. Any ideas?

well.. if it's a powered antennae, was the wire connected?

Was the antennae plugged into the head unit?

If that's true.. then the reception on the aftermarket just sucks..

Its not a powered antenna and yes the antenna is connected. I tried both with and without the "power antenna" wire connected on the aftermarket harness

Do you have a standard antenna or a small one one the roof?

Her car had a standard non powered retractable antenna that comes up out of the a pillar towards the top. We tried with it in and fully extended. Still fuzzy.

Thats what she said.
