Hi friends today I came with a Fiat 500 in the workshop,the customer tells me that the car due to a collision and have had to change the dashboard.In the change have mounted a dashboard with steering wheel controls,aux input/usb,blue&me where on this car were not fitted before.
Now the customer complains that the steering wheel controls for car stereo work properly but other buttons such as voice and answer the phone do not work.I tried to make a diagnosis in the system convergence but I do not own enter.I checked under the dash passenger side and there is a control unit of black color with a blue socket and I think it's the convergence of this car.I wanted to ask if anyone knows if this car is the convergence of the port behind the dashboard passenger side because I remember that in models '07, the led on the rear and if it has a wiring diagram for the system blue&me to this car, where can I check all the connections and associated power supplies.
