Car Stereos: Aftermarket Sereo in 2009 Toyota Camery, antenna wire, pioneer stereo

Question
Ok, I just changed out the factory stereo with a Pioneer stereo/Nav unit.  When I disconnected the old unit it had like two antena wires (Smaller Blue) and (Larger/Normal White) The Aftermarket stereo only has one Antena Hole.  The Reception sucks for the Radio.  What can I do?  What's the deal?

Answer
Kevin, the antenna wire is the large black wire with the big round "RCA" looking plug on it, and it can only be plugged into to the aftermarket radio's receptacle.  Any other wires should be for power or speakers or capped off.  Double check your wiring diagram and be sure your antenna wire is plugged in securely.  If it is loose, you may need an adapter plug for your antenna.  Hope this helps, Scott
