i installed a clarion cd player in my a4 last night and used one of those european to japanese antenna adapters. now the fm reception sucks. i noticed that there was another wire coming off the factory antenna harness to the stock head but i don't know what that was for. can anyone help? thanks<p>-mather

you need to get a POWERED antenna adaptor. They make one for VW/Audi. It's a cylinder shape aluminum tube about 6" long and 1/2" diameter with antenna plugs on both ends, and a power lead wire. You simply plug the factory antenna lead into one end, and plug the other end into your new radio. Then, you hook the lead wire up to the "power antenna" lead on your new radio... and viola! you've got radio!

The adaptor is available at any place that sells stereo stuff. It's a standard VW/Audi powered adaptor... any place that does installs has to carry it. It should cost about $8 to $10 bucks.

Basically, hook the power antenna wire from the new head unit to the blue or red wire from the power antenna adapter. Then hook both of those to the blue wire from the wiring harness. To insure its the right wire, this should be plugged into the plugs which come from the car and it should be connecting the white wire from the car.

So, White wire from car connected to blue wire (via wiring harness) connect blue wire from harness, power antenna from head unit and wire from powered antenna adapter together.

Then connect the other antenna adapter parts to the car and head unit.

Here's a quick picture if that didn't make sense:
