Is there a quick way to reboot the unit without shutting off the car and restarting? Pushing the reset pin hole button is not an option since that resets all audio eq settings.

whether you turn off your car and turn it on, or press the little button you're going to still have to boot up.

But no there is no other way. Unless you push an 'emergency switch' in the ACC line and only flick that when you have to

I know I'm still gonna have to wait for the long boot... I just don't want to kill the engine. I was messing with map display stuff on my laptop while a friend was driving and had to wait until we were stopped before I could add my latest changes.

ya the only way is a switch on the ACC wire
