Homelink is located along the top of the MCU screen. Select the 'house' icon and you can set it up.
Heated steering wheel (if equipped) will be in the climate control section (click the fan icon on the bottom of the MCU) and look towards the bottom left of the screen for the heated steering wheel toggle.
Note that if the car does not have the subzero package w/heated wheel, that option will not be there.
