Frankly, I think that's part of something too expensive, but an alternative of another manufacturer in the US, where a very good support provided to a very stable leather belt loop for secure closure of the GPS and it turned out to be resilient is, regrettably, no longer marketed.
Therefore the Garminfreund has no alternative in my opinion and should take the lush price for not very stable part in purchasing.
I will order now mostly in a double for the spontaneous replacement in case of failure.
