Hi to you all, I have defected from TomTom and purchased a Nuvi 3598 and I love it (only had it a day :-). I have loaded Garmin express no problems and the unit was updated accordingly. I have 2 questions, first the voice control does not work for find place etc saying "this function is not available in british english" although volume etc does. and secondly how do i do a master reset? the ones shown on you tube is for a pressure type screen and not glass
thanks in advance
