In our Honda Odyssey, we have been just streaming direct from our phones using a lightening/HDMI adapter and it works pretty slick. For toddlers you can control what they are watching from the front seat with the phone vs from having see what is on the screen like you would have to do with a firestick. If you take a call it does stop the stream but I tell myself I shouldn't be on the phone driving them anyways.... I envisioned someday I could use an old phone dedicated for the car with it's own data plan vs purchasing data on the vehicle itself. Added bonus if that works is that we could move the phone between the van and future Yukon XL (I've been waiting since May).
