I believe there is a better way
IF, your 5" radio has a microphone port
Run a wire from the radio to the drivers side "A" pillar & place a microphone in the pillars close off panel, close to the windshield, above where the panels screw sits.
The reason that i suggest this is the microphone that is within the rear view mirror almost requires you to close your windows & turn off your climate control fan, so that others can hear you speaking
There is a note in your owners manual that suggests closing the windows & turning off the fan
The microphone in the rear view mirror picks up the fan noise & any cross wind when the window is cracked open
Some ppl choose to place the microphone in the overhead console forward of your face a bit.
Just drop the overhead console
drill a hole through the console itself without penetrating the overhead roof liner, if there is foam on the back of the roof liner, carefully remove the foam
fit in a microphone & run the wire down to the radio
I know you can do it, i have the 2" speaker mounted in my overhead console, it is mounted where the console curves up to height of the roof line, below is a image, look for a small dark circle where the console is removed but the roof liner is intact
