Too Much Data Usage

I’ve had this app for 24 hours, and it’s already used 169 MB of data from just existing in the background.
That said, it still has the potential to save my life. Hopefully I’ll remember to turn on its ability to use data before a long trip or something.

So Far, So Bad

I signed up for OnStar the other day and they asked me to download this app but so far all it seems to offer is to show me on a map where my two phones are. Big deal. I can’t seem to do anything else with it.
