ive got the RJ-45 connector in base of console and the small mic on the a-pillar, just wondering if I will need to install the speaker that came with my hands free kit or when I splice into the RJ-45 connector per the Cell Phone Integration with Nokia 61XX FAQ will I have sound from some hidden speaker?

Current Bose-equipped cars have a small separate speaker just above the left driver's, wheras non-bose cars have a dual-coil speaker that serves both purposes. I think it has been this way ever since Bose appeared as an option.
