The mumbi Schoockproof Bag is perfectly adequate for the Navi TomTom Start 20 even! But I want to store the charging cable in your pocket. And both things do not fit! So if you want to pack only the Navi because the charging cable remains in the car, is well advised with the bag! If you want to store more, must take a bigger bag! I've now ordered me this bag, "Navitech carrying case black Eva Nylon Case for TomTom XL, TomTom Start 20, XL, VIA 120 + 110"! The ideal is my purpose!
