Many cars now have a kit free hand system that is done using a bleutooth bridge between the vehicle and your smartphone. It is very well to avoid the distraction of the driver, but the negative effect, it is the consumption of the internal battery of the phone. What could make us think before connecting to his car when the battery is low. This is why it must be in the passenger compartment of the vehicle car charger, which will plug into the cigarette lighter. Here I speak of the Inateck AL 2011 car charger, which is a car that has 2 USB port (to connect any device) it is directly linked with a cable lightning (Apple).
