just out of curiosity, before i bougth the f500bt, i had my car installed an f90bt + all the necessary harnesses cuz i wanted everything works like the factory, but this store cannot have the factory installed dvd work. before they told me they cannot make it work, the f90bt was already in my dash replaced my old one. they wanted me to replace even my factory dvd and install another one. so i tend not to agree and had my old stereo put back. any of you guys have any idea if this f90bt worked with my bose system? thanks for the feedback.
