I have the UAS, it’s a 2019 Classic. Just upgraded my manual dim mirror with an auto dim with smart beam. Did not appear that I needed to replace the header harness. I updated all the settings, I have the soft key for the auto high beam, but I don’t see one for the auto dim. I also confirmed for auto high beam, it indicates it’s on/off in the EVIC when I turn the high beams on/off, I just haven’t tested everything while driving at night yet. Just can’t find a soft key for the auto dim anywhere. Assumed it would be under the mirror settings but it isn’t. And I’ve checked a few other places as well.
