Thats one of the issues with the newer radios I have notices. The AM/FM part SUCKS! The stock radio was great in receiving stations. I have the same issue but not so bad. Im not sure exactly what wire your talking about that was wrapped around the antenna wire though.

I would search to make sure the antenna size that is on the car is correct for your radio. Some of the newer radios are designed to work with small antennas that fit in the window or even smaller (such as the shark fin on the Audi's)
