| If a radio navigation unit from one vehicle is fitted into another vehicle, it is essential that the part number of the replacement unit is the same as that of the unit previously installed. Otherwise faults will occur with the navigation because the turn angle sensor setting in the radio navigation system will not be compatible with the vehicle. |
