Abstract
A method of manufacturing a vehicle rearview mirror system including providing a reflective element and providing a common circuit board having first and second circuit portions joined with a breakout interface. The first circuit portion is populated with electronic components and the second circuit portion is populated with at least a compass sensor. After population, the first and second circuit portions are separated from the common circuit board to form, respectively, first and second circuit boards. The first circuit board is disposed at the rear of the reflective element and the second circuit board is interconnected to the first circuit board.
