This page describes the install of the Beltronics /Escort / Passport Smart Cord in a 2011 Subaru Impreza WRX. The process will be the same for all 2008-2014 WRX & STi models and Impreza models up to to 2011. The process will be similar for other models and model years.
Parts for the above-mirror mount consist of a universal phone/GPS mount from Amazon and a bicycle seat post clamp (Amazon or any bike store):

Test fit of the mount above the mirror. The benefit of this is to get it up and out of your line of sight (and to make it harder for a cop or thief to spot it) while having unrestricted view of the road ahead.

The wiring was routed to the lower cubby, just forward of the shifter/console:
I secured the mute button / display for the SmartCord with 2-sided tape:
