ok i just bought a pioneer radio today for$20 and i was trying to find out some info about itill post some pics of it in a min
im assuming by oxizilary port u mean the audio input from a 3.5mm cord coming from ipod/phone/mp3 player??
idk how you are on the electronics front but you could disassemble the radio enough to get to the port unsolder and install a new one, assuming the port itself is bad and nothing else.
Also if the port being bad doesnt bother you then i'd just leave it alone, i really like my input i hardly evr listen to the radio anymore.
You hooking a system up to it?
oh well then it doesnt really matter if it works or not, but yeah it is really nice to have its all i use on my radio
