No, I didn't consider price of each individual option. If that is as far as one is interested in upgrading, sure, your approach and others were good ones. My perception of the cumulative posts was that the end goal was moving toward upgrading to current available features, as the posts mentioned aux and hands free phone and potentially replacing the radio. If that is where you will end up seems to me it would be easier, I suppose it could still be more expensive. to bite the bullet from the get go with the bridge so there would be one device handling everything while utilizing the existing components. I am not in any way even implying anyone took the wrong approach or wasted time or money.
