I've got a 2011 Forester that came with the auto-dimming mirror with the compass display in it. The compass display has died, so I thought I'd take the opportunity to upgrade to the mirror with homelink so I can ditch the garage door opener clipped to my visor. How hard is it to swap in this mirror? Is it as simple as removing the old one and plugging in the new one? Looking to hear from someone who's done it before. Thanks!
