I am normally a paranoid kinda guy, but reading this post made me rethink that maybe I'm not all that bad. All of you who are worried about some hack clicking around inside your navi DO realize that all they need to do is open your glove compartment and look at your registration if they want your address, right? Personally, I only let a mechanic I trust touching my car, and I don't valet; not because I'm scared of them getting my address but I don't want just any random person driving my car.
Just because you're paranoid doesn't mean everyone is out to get you
Oh yeah, and edit: first post! yay! lord knows I've been a lurker long enough!!!
