I think they just mean a bluetooth solution that uses the car speakers and an external mic. I thought I needed one in my Miata (with the top up), but turns out the built in speakerphone works good enough when the phone is mounted on the dash. With the top down, nothing would really work, LOL. Not a setup I would want to use for business calls, but I would not want to conduct business while driving anyway.
