So I wanted navigation but I have no desire to pay 13€ a month for the privilege.
So:
Go to the App store and download navigation of your choice on to the Arkenstone.
Open nav app.
Starks own App will force screen change over to itself once active. Wait until it's showing the "dash".
Select home (3 horizontal lines)
Select the square button on the right. That I'll show all apps currently open.
Tapp on the logo at the top. Select split screen and select the other app you want to be shown.
