My guess is that more would than wouldn't. By a seriously long way.
I daresay they would. The easy functionality is a strong inducement, even if you are aware of the slurp and tracking, even the feeling of your lifeforce being constantly drained by the knowledge of the slow drip of your personal data and activities syphoned off to feed the Google beast is not enough for many users.
But having the choice not to, if your don't need or don't want the thing leeching at your life is much better.
There are other satnavs, and openstreetmaps (is that still about, I lose track) could do with the attention. One Google fan (or even one Google van) certainly didn't make Street View the rich resource it is.
