Has anyone installed an auto dimming mirror themselves on their Prius C? Planning on buying one for my C3. I saw an install manual and it didn't look like it would take that long to do, BUT, being someone who's not that handy, I don't want to wreck my new car Called a dealership and they quoted me $100 + tax for the labour. Is it easy to do? Any tips/pictures? Any advice? Thanks a lot!
