Hum, interesting. My truck is the same model, but 2020 and I haven't been to the dealership since purchase. I assumed it was an OTA update. ???
Now, my truck came with tow mirrors and I did switch them to OEM sport mirrors that have the same features, plus auto dimming on the right mirror, about a month after purchase. I cant remember if I checked the reverse tilt after I installed them, but I cant imagine changing from tow mirrors to sport mirrors (again same features) would change the auto tilt feature. Can someone on here with factory install sports mirrors check and see if their truck has dual or single tilt? Also, how to you check to see what software version is installed?
