Factory or aftermarket nav?
The ignition absolutely is a necessity. This will trigger the stereo to turn on when the ignition is engaged (car is turned on).
If you want (assuming you can't or don't have the ability to utilize the wiring harness) you can splice into the red (positive) wire coming off of the cigarette lighter. This is what I used in my install, I wasn't using a wiring harness.
