Yes, I've done it with my car without any major issues. Follow the thread posted above to disassemble the map light switch cover (requires a small flat head to pry the cover).
Route the mic cable through the A-pillar and tucked underneath the headliner (same as one would do when installing an aftermarket rearview mirror). The mic can be pushed through the headliner through the opening of the map light cover. Tear the dust cloth out of the map light cover, use masking tape to hold the mic in place, and use epoxy to permanently attach the mic.
