Good info, What is your phone telling your rental car?

Never thought about that. Of course, we've only rented a car once in the past six years. So it isn't a huge worry for us. Still something to keep in mind.

I don't drive so never rent a car. Don't even have 'my location' turned on my mobile or bluetooth. Only place wifi works on it, is at work!

I do however get emails downloaded to it etc and some facebook stuff.
