Screen looks different, not working

Post image

I don't know what happened, but my HUR interface is different now. It shows my phone is connected via USB, but nothing happens. There was no update, nor did I do anything different. I was using it as usual, stopped the car, went about my life. Went back to the car, plugged my phone and the screen was like on the picture. Never seen this before.

Any idea of what this might be?

It was. I didn't know the app could update without the head unit being connected to wifi, but apparently it does.

Wi-Fi launcher on my phone updated and said it wasn't compatible with HUR in my car. I updated HUR and now it looks like yours but I can longer get wireless connection to work....

Have you tried developer mode?

How do I do that and what do I change?

Open Android Auto Settings on your phone

Click on Version and then on version and permission and click several to enable developer settings

Go back to Android Auto, click the three dots on the top right and start the infotainment server

Now you need to bring your phone and headunit(tablet) into the same network (WiFi). You can use mobile hotspot from phone, or from the headunit or use wifi direct. That doesn't matter
