Question [Q] Car Dock (or lack of) Recognition?

This has happened a few times now where I plug in a generic charger in my vehicle and I get a message in AutoGuard that it says it's recognizing a car dock.

So that brings me to the question, how does it recognize that there's a car dock? I'm guessing in the genuine Samsung Car Dock there's something in the dock itself that tells it it's a dock. But with that said, how come it's periodically recognizing it when I use a cheap generic car charger?

Strange...

Any tricks to let it go into car dock mode when plugging in a charger in my vehicle?
