I'm the total opposite. I love my in-car nav. I have a shortcut on the steering wheel that brings up a list of recent destinations, so starting it takes literally seconds. I don't have to plug in my phone, or even look at it. I get turn by turn in the binnacle AND the heads-up display. And on top of that, it _doesn't_ do all the silly stuff that Google does to make people think it's so great, like routing me through some residential neighborhood to save 45 seconds. I'm okay taking one freeway vs another, maybe (I don't like adding miles to my trip), but that's about as smart as I want my navigation to be.
Maybe this is because I don't commute by car though. If I get stuck in traffic, it's the one time that month, and I've probably got a podcast on anyway.
