I don't believe that this in entirely true. On my 2DIN head-unit, I never exit iGo and all of my setting changes still get saved properly - so it can't be writing the settings changes only when you exit iGo. I've found that it writes the changes as soon as you make the changes - at least on my 2DIN unit.
I know there is some "debate" about whether or not you need to exit iGo, but on the 2DIN radio I use (a Rosen DS-GM1010-P11), the manufacturer even specifically *disables* the exit button completely on the version of Primo that comes with the unit - so you couldn't exit iGo if you wanted to. While I'm not using the version that came with it, I still never actually exit iGo before I turn off my car - and I've never had any issues whatsoever.
I'm not sure if the car head-units handle something differently or what, but turning the car off without exiting iGo first has never caused any issues for me - and obviously, the manufacturer wouldn't specifically disable the exit button if turning it off without exiting would cause problems. iGo definitely does have to restart from scratch every time I start the car (it doesn't just go into "sleep" mode or anything).
I don't know of any automotive GPS application where you have to exit the application before turning off your car...
