Is there a driving mode? can't find anything about it on the phone... (I'm talking about where you can set it to where if you make a blu-tooth conneciton, like in my car, it will reply to txt messages for you... that your driving ect...)
There is one. I think by default, it'll switch to it using the OEM car dock, but there's also "Car" in your app drawer that takes you to it. I haven't played with it much to know what all it does.
It's there. Best way to access it without a dock is a car home app like the built in one or Car home Ultra. I set up Car home Ultra to automatically go to car mode when it connects to my trucks Bluetooth so no special dock needed. You'll need to get a third party app for the auto texting thing but voice commands and voice texting work reasonably well over Bluetooth. Just hold the talk button on your stereo for 2 seconds
