I have a Europe MK4 DVD nav running 27.1 firmware with a 2006-2 map, can anyone tell me if it is possible to enter just the post code to find your destination as when i go to the address input screen i cannot enter any numbers or am i doinig it wrong, if so can some one please explane the procedure for me. also the arrival time apears to be about two minute out, not that this is detrimental but i just wondered how it would affect your arrival time on a long Journey i.e estimated time of arrival
