I've had 2 GPS fail because the mini USB connector broke from the board inside. No warranty because "the unit was abused and not used for it's intended purpose."
I now have a Delorme PN40 which has a very robust connector powered by a BurnsMoto usb plug hardwired to the battery.
Great for trails but wont navigate you through town.
The odds are good that the goods are odd
