After a 3.5 "Navi I now have a 4.7" Navi (Medion GoPal) and a new bag was needed. The mumbi bag protects my Navi and is also more pleasant to handle. Prior to the 3.5 "I had a leather slip case with magnetic closure which was quite cramped (but the Navi looked after 5 years still as good as new), the mumbi-Tache has more space (up to 5" devices), inside two chambers, soft lined, with a network and a 3 rubbers, among which the Navi is pushed. I use the bag only for the Navi. Cable I take with rare, possibly (I Autoladefgerät in the car) the USB cable, but it is already close and you have to lay the display down so that it is not damaged. If you want to use the navigation system as a pedestrian, can be in the network some money and papers and you take has a comfortable pocket (eg while walking in a strange city). That's a good solution. The bag has a strap and can be worn well, the bag should fall again, the Navi is well protected. The price of this product is very good! I can recommend the pocket much.
