A vehicular rearview mirror system comprises an interior rearview mirror system that includes an interior electrochromic reflective element that assumes an interior mirror electrochromic reflective element partial reflectance level in response to an interior mirror electrochromic reflective element drive signal. A housing is provided for the interior mirror electrochromic reflective element. The vehicular rearview mirror system includes a circuit board and a digital electrochromic drive circuit, the drive circuit supplying a drive signal to the interior mirror electrochromic reflective element. The vehicular rearview mirror system includes a garage door opener; the garage door opener including a transmitter and a logic circuit for transmitting garage door opening signals. The circuit board includes a microcontroller shared, at least in part, by the electrochromic drive circuit and the logic circuit. Preferably, the microcontroller controls over a vehicle network at least one other vehicle function, such as a driver-side electrochromic mirror function or a passenger-side electrochromic function.
