I completed the humidity sensor upgrade a while back for the auto temp control. Decided to do the mirror upgrade to get SmartBeam enabled seeing how I had the right wiring from my M2Mods wiring harness. Found a mirror on ebay and installed it. Couldn't get it to work, then found I needed one additional setting which was under a 2014 CBC I/O & Features, who would have thought a 2015 need a setting under a 2014 menu! Not me, I skipped right over it! Anyway, after enabling it I'm now good to go with SmartBeam enabled.
