It looks like you have the current version of the same head unit I installed a couple of years ago. One of the best things about this one is that it doesn't have a brand logo on it's face so it's not quite so obvious that it's an aftermarket unit and it's also easy to change the home screen to something that looks like it could be OEM.
You'll really like the GPS speed function on the Torque app as it is far more accurate than the car's speedometer.
