The belt clip is an important accessory, if, like me, often comes with the Garmin outdoor navigation through the terrain. Positive on the part is that you can easily raus the Navi and can shove and if it's in there, then you can also rely on it, that it is firmly seated. Would be stupid if the 500 euro expensive Navi suddenly falls down and nobody notices. However, this flexibility comes at the price instability. I use already my third belt clip. Both predecessors existing plastic mount has erupted, when it has jammed accidentally while sitting, which can easily happen again. Since there is no alternative for the part, you have to buy, as it is in Garmin. The best equal to one in reserve, in order to stay fit for work when the part breaks. By the way, even the small metal pin, which is screwed into the Navi and the pressing the Navi in the belt clip, like breaking through times. Again, you should always have a spare part at hand.
