i have a 2002 maxima with bose w/changer and navigation

am i able to just pull out the bose deck and hook my navigation system up to a different deck? any specifications on what i can or what decks i can use...it is irritating the crap out of me how bad my fm modulator that i hard wired...compared to the bose cd player...it really sucks....

is there a way i can disconnect my bose changer and just hook it up thru that aux? or something like that...any suggestions
