Im curious to see how much this drains my battery on my brand new iPhone. I selected the option to only use wi-fi to send data, but you are required to leave location services running all the time. You are also required to leave Bluetooth on. Technically, you could turn these on each time you get into your car and off when you get out, but who is going to remember to do that?! It should be easy to at least indicate that location services should only be used when the app is communicating with the Bluetooth receiver. Im not sure it will be worth the discount.
