I think this is a great option for someone who wants to integrate other functions . I value the bluetooth streaming and the wheel controls more than I do the navigation. My wife has navigation in her truck and I would rather use my iPhone than try to use the truck one.
I would consider this as a great option not because of the gps function because at the end of the day, I know where I am going, I don't need the car to tell me. however this allows me to integrate other functions that my current "professional" does not.
Price point is also great.
I will wait to hear from you OP on how it does and how the car reacts to the electronics.
I am also curiose to see if it will read the MPG, Range, and other functions that the Professional does.
