Well, this is probably a long shot of anyone knowing. But I was wondering if anyone knows 1) If you can access the On Board Diagnositics through the car, and have it display on the navigation screen. 2) If anyone knows how to do this.

Some may think I'm crazy, but you can do this on about every Cadillac built.

 

i wish!

 

I bet there are some hidden menus (like easter eggs on a DVD). I'd like to see a real time readout of fuel consumption.

Yes, you can. Turn off radio and have car on (running). Press the Menu button and at the same time move the volume **** back and forth until you see the diagnostics screen. I have a 2018 Maxima.
