Antenna reception is poor

[wrek]

I have a Chevy Tahoe 2007 LS.
I just finished installing a Pioneer Avic F900BT Navigation system. I used a GM onstar adapter with the system.

After installing it, my antenna reception is poor. There is a blue wire from the deck labeled Antenna but I dont know where to connect that to.
Any help is appreciated.

The blue wire is for a power antenna, do not hook it up to anything.

After installing the Pioneer AVH-P6000DVD I too noticed that my radio reception isn't as good as the factory stereo was :cuss:

My factory HU has horrible reception. I have found in the past that after installing aftermarket HU the receptions was much better. Maybe you have a bad connection?

mine is horrible!! I installed to Kenwood 5120, and it sucks. I also got tint on my windows and the shop warned me about reception..

Is there anything i can do to fix it?

I bought the antenna adapter and cant even get AM stations either.
