My turn to give back, albeit in a small way. Found an easy, seamless and unobtrusive way to install mic with a secure setting. Conversational tone works perfect and believe it or not, fine with window open or closed. Note that it is close to source, pointed functionally directly at your mouth, and cannot get in the way, even when washing windows. The rubber sealing also folds over the ball hiding it, and the mic is very secure.

To run this, put an small LED flashlight in the HU cavity facing towards the driver's door. Remove the fuse cover on the driver's side of the dash. Look in and espy the LED light in the cavity (there is only one very small spot where this shows, and without the light it appears impossible to know where the cavity can be accessed). Take a straightened hanger with a hook bend in one end (needle nose pliers to create this tool), with a 90 degree three inch bend at the other end. String hooked end to the light in the cavity. Grab the mic with the hook. The opening is small enough that I had to twist the mic to get it past to places it appeared to hang up on, and that's the reason for the three inch bend (to twist the hanger, hook, and mic inside the dash). String the mic wire under the rubber adjacent to the fuse cover, then up the A pillar rubber to the placement in the photos. Search as you might, there is not a tenth of an inch of wire visible anywhere. Although it may appear to be a concern while you're doing this, it does not come within a country-mile of being impacted by the door operation and is completely unobtrusive to entry and exit.
