Directions API with Arduino Uno and LED

Hi guys,

Pretty new to this! but Im trying to connect my Arduino to an Android app (That I would develop) through bluetooth and use a google maps API or something else to send turn by turn directions and light up arrows when a person needs to make a turn. I don't know if Google maps give access to real time turn by turn directions on their API. Not sure but you guys may be able to help. I just need a way for my Arduino to know that there is a turn coming and light up an arrow accordingly.

Thanks, B

Where do you solder the wires on the software?

How is the Arduino supposed to know where it is? How is the Arduino supposed to know where you want to go? How is it supposed to know how to get there?
