I have retrofitted my navigation system. Is is however possible to use a FISCON Bluetooth handsfree?
It doen´t matter if the navigation system was installed from factory or retrofitted. It is even not important if the navigation system is normally compatible to the car. In that case and depending on the car the operation from the multifunction steering wheel or the data on the FIS display could be not available. The operation from the navigation system itself is always working.
