The invention relates to a method for authorizing external devices that can be optionally connected to a data bus of a motor vehicle. At least one first code can be input by a user into an external device that can be connected to the data bus and is forwarded by the external device to an authorization device of the motor vehicle via the data bus. The authorization device compares the first code with a second code and, in case of agreement of the first code with the second code, the device connected to the data bus is authorized to couple to the data bus. The inventive method is characterized in that the second code is determined on the motor vehicle end independently of the external device and the second code or an alternative code suitable for determining said code is output in the interior of the motor vehicle by an output unit. |
