Hi. I've just installed a Pioneer FH-S500BT radio in my 2007 Altima S and the radio reception, both AM and FM, is very poor. The antenna adapter seems to be properly plugged in. I wonder if anyone else has had a problem with an aftermarket stereo? Also, the adapter kit came with only one plug adapter so the smaller plug for the stock radio is not being used. Does anyone know what this plug was for and what effect there might be without it? Any help would be appreciated.
