I have a car that supports Bluetooth transferal so I can communicate without the use of holding my phone. To save on battery life, I have a widget on my phone that turns the Bluetooth setting on and off, so I only have it on when I'm in the car. However, I sometime forget to turn the setting on, which causes a hassle to answer the phone. Therefore, is anyone familiar with an application that could help me automatically switch the Bluetooth setting on when it detects I'm entering the vehicle? I've heard of location-based applications that are able to switch certain settings on your phone (i.e. turn Wifi on when you're at home, etc.), but my car would be considered a "mobile location" in that scenario, so it would not suffice. Thanks ahead of time for any suggestions.
