After already killing one SmartPhone, I found a very good cover for my SPV.
It’s not listed in the compatible phones but it fits like a glove on my SPV 100. Furthermore it’s waterproof (boat, ski) and dust/dirt proof. I am very happy with it.
Check www.boxit.net and look for a normal small size cover. I think it’s the standard one. It also works without taking the phone out of the case.
Cheers.
