I was sitting in the car waiting for my wife for a long time last week. I found that the car has a wifi hotstpot in it! (I do not have mobile prep high in the car). I couldn't find the password so I opened the hidden MMI menu and found the password. I can connect my phone and tablet to it but since I don't have the sim-card option, it seems a bit useless. Do all new cars have wifi? Or do I have an almost complete setup for getting mobile prep high? If so, then what would I need to get it working with google maps/traffic?
