My mic is currently run behind the trim piece on the driver's side of the windshield then under the headliner. It is adhered to the middle of the windshield close to the rearview. Seems to be decent so far.
Eatinitup - Keep in mind you can use AppRadio for free nav on the AVH series. That's why it wasn't worth the extra bucks for the AVIC for me.
I would love to get this radio static issue sorted. Such a pain in the ass.
