Gentex 85ADFMCHV Frameless Auto Dimming Rearview Mirror with Compass & HomeLink - Compatible with VW/Audi (Includes Bracket & Wire Cover) - Perfect for Night Driving & Enhanced Vehicle Safety

Installed into an Audi A4 (2007 2.0T Quattro - Base sedan) as a replacement for a standard rearview mirror. Main reason was for the homelink integration that was missing in my car and my hate for having a garage door opener handing off my visor. The compass was a bonus. Install was simple enough and easy to wire in using fuse taps (not supplied). It's a minor upgrade, but the frameless design fits the car nicely. Install took about an hour - mainly because it took time to identify the switched and constant 12V points to tap.
