compass/mirror
I successfully installed a compass/autodim mirror last night! It's from an '03 Camry. I got it on ebay for $76 and it looks great and works perfect. I used the Homelink instructions to find power (ACC) and ground.
http://www.vfaq.net/mods/ECMirror.html The wiring is NOT present, but just to run power and ground is no big deal if u follow the above web site instructions. It's just oh-so-slightly longer than my standard mirror (non-homelink, non-autodim). No issues with the sun visors at all. I will try to post some pics later. Any questions just ask me. This is the 3rd accessory I've installed myself so far (mudflaps and oil-drain valve). Drive fun, drive clean, drive Prius!
