Radio Static - BMW Forum

I just replaced my factory head unit with a pioneer in a 2000 328ci. The first thing I had to figure out was finding the power lead for the factory amp to make the speakers work. I did that and now the channels (fm and am) have really bad reception. Some stereo shop told me that there is an amp for the antenna that has to be tapped into a remote turn on. I do have an antenna on the roof so I don't think there is one in the window. Anyone have a problem like this.
Thanks

The antenna on the roof is most likely a cell phone antenna. the radio antenna is in fact incorporated into the defroster grid in the rear window. The antenna amplifier is located underneath the left rear c-pillar trim on the inside of the car.

I did some research and found out that not only do you need an antenna adapter, but you need one with a lead on it. It is commonly used for VW's but if you have an antenna with a booster like I do, you need this also. The part seems to be special order for the late models of BMW. The factroy radio sends a small amount of voltage directly through the coax cable for the antenna. Aftermarket units do not. That is where the adapter comes in.

Absolutely correct, however Opel, Audi, and Porche has the same setup. The data base where you bought the unit should have suggested it.

Are you sure that the I need that adapter with the lead on it. I have had some people tell me no, and then others tell me that I do. Does anyone have any experience with this?
Thanks
