If you drive for work, this product allows you to track your travels for taxes. This product takes less than 5 minutes to install in your car’s OBDii port, and link to the bluetooth app.

This unit reports to the cloud via 3g.  The trips can be marked as for business.  If you ever have a need, you can download the route you drove, exact mileage as well as other stats that are revelant. At tax time, you can prove each trip, with mileage.

You can also ping your car to locate it and many other features that you can read about on their page. This device will also call the people in your list should an accident occur. This is almost like Onstar, but without the ongoig fees.
