Radar, the trip meter, radio, Bluetooth, etc functions are all on the joystick. I would suggest getting an operator guide for the 2019 as describing the process in a post is difficult to get exactly right. Very roughly…..you press in the joystick to open the Home Screen. You then press right to take you to the sub menus, and then press up and down to take you through the setup, phone, etc sub menus, and press right to see sub, sub menus under each heading.
