I'm not new to Navigators having owned a few in the past but it took me almost a year to realize that when I change the temp of the HVAC with the primary (driver's side) temp control that it only controls that side temp. One day I was driving and noticed I had heat coming out my side but cold air out the passenger side vents and when I adjusted the passenger side temperature it was still at a low summer setting.
I tried turning it off and on and putting it on AUTO mode where it shows one temp on screen that you can adjust but once I adjust that if I hit the passenger side temp adjuster button the passenger side temp setting will come on and it won't match the driver's side. Most vehicles with dual zone temp have a dual zone button that turns on or off that function.
Is there a way to raise/lower both temperatures at the same time?

I'm not a fan of "Easter egg" functions, but that does seem to be the way things are going -- at least with "mobile" interfaces on things like smart phones.
