Got my 2017 1500 reg cab lone star last weekend. It has the 8.4. I have read all about the nav upgrade and where to get that but I do have another question regarding the voice commands. Can the 8.4 control the climate with the voice commands? Everything else ( music, phone, sat radio) I have no problems but I want to make sure it can actually control the ac with voice commands becaus, frankly, my neighbors look at me funny when I'm sitting in my driveway telling (yelling) my truck "Set temperature to 75 degrees!" One neighbor ACTUALLY pulled her kid closer to her when she walk past my house. I heard her, "Stay away from that man Jimmy."
