Seems odd to me that out of the dozens of bits of truck info I can display on the screen while driving, a simple voltmeter is not one of them. I wonder why this previously common (and increasingly important) bit of info was left out of the options.
I suppose the simple cigarette lighter powered digital voltmeter / usb will have to do. Funny though, sticking a $5 trinket in an $80k truck. ;-)
Voltage is displayed on the general measurements screen as @powerboatr stated, the only thing to remember is that the granularity of that display is 0.5V.
I love my $5 plug in. I actually put one in my other vehicle. No scrolling to find voltage just take a look at plug in. Checked with a volt meter and was spot on.
