ATTENTION! ! ! THE sound totally inaudible by car .. especially if you're running radio Testing done on several new Tomtom this range (start 40 50 and 60) At Auchan, Boulanger, Carrefour. Same problem on ALL of his. We must come to model approximately 250 (GO) to find good sound I made this gadget more little indication Shared the useless products Garmin offers perfect sound from the basic model (and especially they are cheaper)
