hmm...okay I guess I was assuming if the external auto dimming mirror had rear/front photo sensors they would be obvious, to which I havent heard.
...anyone see any pin holes in the front/rear of their external mirror that could be the sensors...?
If you cover the front one up with your finger - does it dim?

for those with auto dimming rear view mirrors and external mirrors - if you cover up the front sensor of the internal rear view mirror - does it turn green as well as the external mirror - or just the internal one...;>)
