The new 2020 Corolla hybrid.

It depends.

You can use Mirrorlink (Samsung phones have this installed and ready to go). This allows you to mirror whatever is on your phone, onto the screen. I don't have a Samsung phone so can't try it, but my son's phone plugs in via USB and the Mirrorlink prompt pops up automatically.

If you mean the connected services, make sure you install the MyT application on your phone and go through the vehicle verification process.

Once this is complete, you will need to take it into the dealer you bought it from and show them your MyT application screen that says that the car needs to be 'activated for connected services'.

Our local dealer didn't have a clue so I had to go to the dealership I bought it from who did it for me.

I hope that helps.
Just bought a 2020 Corolla Hybrid Blizzard Pearl yesterday - we traded in the wife's 2008 Nissan Maxima. My wife drives 50 miles per day for work, should be a major difference! She loves the car so far!
