Like many, I recently received the email notifying me that my complimentary Premium Connectivity would end 12/31/19. I could continue by subscribing for 9.99/mo.
I have unlimited minutes and data with Verizon on my iPhone.
I tried to connect using my iPhone as a wireless hotspot. And lo and behold it worked. It continued to stream music and the satellite map view. I also pulled off the road using the hotspot and all the entertainment features continued to work.
I'll post an update after 12/31/19.
-enable hotspot on your phone
-tap the cellular icon, upper right screen, and select your phone as the wifi source
-enter the password on your phone, enter and enjoy the hotspot.
For the vast majority of my travel I am within 1hr from home with excellent cell service from Verizon wh/ gives me a strong hotspot.
If you don't have unlimited minutes 10/mo is very reasonable.
