Thanks for the information. For the cost of the bimmer system reported by you, considering that the car I am dealing with is very equipped and should cost much more than the price requested, so if it is possible to develop the audio system, I prefer to take it and then spend it a good system, rather than taking another car with a superior system but less accessories.
