  • detecting an incoming telephone call;

    determining a distance to a forthcoming route reference point or to an output of a forthcoming manoeuvre instruction on a predetermined route in response to the detected telephone call; and

    delaying the signalling of the incoming telephone call until a manoeuvre instruction has been output if the determined distance to the forthcoming route reference point or to the output of the forthcoming manoeuvre instruction falls short of a predetermined first threshold value, wherein the manoeuvre instruction that is output comprises a modified instruction in the form of an abbreviated instruction with respect to an originally intended manoeuvre instruction.
