I bought a 2001 factory cd/ cassette player (not bose) for my
pathfinder to replace my 97 factory cd only player, my question is the
new has 1 more plug, not sure what it is for. Everything powers up,
just no audio.

Thanks

Some cars have controls on the steering wheel to control the radio.
This extra plug may be for that or for an optional external amp.
