While the protective case is a bit bulky but is not this advantage? The housing is indeed large enough to accommodate not only the GPS but also all of its connections. Everything returns to the usb cable, car charger but I'm trying, the attachment by suction system. The hull is stiff enough to protect the content which is still the goal. Only small problem, no evidence indicates the direction of opening, we must remain vigilant during handling or risk seeing the GPS falling to the ground ... Conclusion: great product, excellent quality / price.
