OK, I feel guilty about being negative. I would personally buy the Idrive dash and flush mount a cool touch screen aftermarket nav system where the OEM one would go. I feel like your existing communications equipment is piped via the stock radio, and if you pull that out in favor of a new Idrive system, that will all need to be re-wired to work. Also you will need to install a speed sensor wire, since the non-Idrive cars don't have an extra one.
