So the car will use my phone as a hotspot for software updates and to use Google search for Nav. It has built in POI's but google is all encompassing of course. Phones can't be a hotspot while wifi is on. That means get in the car, turn off wifi and turn on the hotspot. PITA.
Genius that I am I got an app called Tasker. It watches for the phone to bluetooth connect to the car. When it sees that it automagically does the hotspot for me. And when I walk away and drop the Bluetooth connection it turns wifi back on.
First world problem solved!!
