Installing HU with Bluetooth - how to route mic wire?
I am considering purchasing and installing an in-dash GPS/Bluetooth, and I am wondering how the Bluetooth microphone cable is typically routed. To the visor or rearview mirror? And where is the cable routed -- over to the pillar, up thru the headliner?
Typically I would mount the mic where you want it....usually on the driver side of the rearview mirror, use the hook type mount that it comes with and just hook it between the roof and the headliner. Put the wire into the "hook" because that always looks neater. Run the wire along the headliner and through the "A pillar" panel. It is easier to run it around the top of the panel where it meets the headliner and then run it down where the rubber body molding for the door seal meets the pillar panel (easier to pull the rubber molding then the panel itself) Most cars have a panel that pops off at each end of the dashboard. it is easier to run it down the passenger side in most cars as the glovebox in most cars can be folded all the way down and out of the way by releasing (squeezing the sides) catches on both sides of the glove box, giving you access to the dash interior and easier access behind the head unit cavity.
