This is from my 2020 display, so the RHO may be different.
If I go to the “Apps” page, shown here, I can long hold any of these options and drag it down to the bottom of the display.
You can see on mine, I’ve set Driver vent and heat on the left, and Pass vent and heat on the right.
Also, my truck auto starts heated seats and wheel if the temp is below freezing.
Again, I don’t currently have my RHO so can’t confirm it works the same… but I sure hope so. These types of customizations really help with an all digital system.
