I've disabled it as the only thing it ever told me was how far away from home I was. I'd drive to work, get out of the car and look at my phone and there'd be a message in my notification bar telling me I was 30 minutes away from home. The last thing you want to see when you've got a 10 hour shift ahead of you.
I find the will so hard to find.
Oh well, whatever, nevermind!
