Navigation Retrofit

The BMW Nav unit incorporates the OBC controls on-screen, while after-market units do not. However, as mentioned above, the Pioneer Nav units generally have some Dynamics Guages, etc that show various aspects of how the car is handling/driving. However, there is no active control of the car's functions... For me, the only one of great significance is the starter Lock Code, since I do use it when parking in areas I where it might come in handy :-)
Hope this helps.

Very good explanation
