Any information out there on what the monthly cost is for the LTE Hot Spot WiFi that comes standard on the 2019 model? I haven't found any info in the manuals or on the system itself. I heard it is thru AT&T. Also is the HOT SPOT only active when the vehicle is running or does it remain a HOT SPOT even when the vehicle is not running? Looking at a way that I can install a Blackvue camera that can monitor truck and stream video/alerts to my smartphone.
