poor reception, need help

Anybody that has any experience with Pioneer head-units, please help me. I recently installed a DVH-p5000mp into my car, and I had better reception with my stock radio. I was looking through the installation manual, and in the notes, it states: "When this product's source is switched ON, a control signal is output through the blue/white lead. Connect to an external power amp's system remote control or the car's Auto-antenna relay control terminal (max. 300 mA 12V DC). If the car features a glass antenna, connect to the antenna booster power supply terminal." My 2000 Nissan Altima doesn't have an external antenna, so I'm assuming that it has a glass antenna. What is the antenna booster, and if my car does have it, where is it located? Thanks in advance!

There will be one or two connections on your rear window other than the ones for the rear defroster. If you follow the wire a short distance there should be a small box that will have an antenna connector going into it. An even better idea is to if you have an antenna adaptor in the car to be sure that you didn't plug it in backwards(I've seen it done and it does cause poor reception) What you can also try is if you haven't cut your factory radio plug yet, plug the factory radio back in and test wires for one that goes 12volts when the radio is turned on.

hahhaha, thanks esmith69, you got it. I was bench testing my deck, and i only hooked up the essential wires (power, constant power, ground, rca's, and the antenna) for basic listening, forgetting about the blue wire. I got so happy that i just screwed in the deck and completely forgot about the other wires. hahahha, GO METRA!!!
