Deda, I know this may sound silly because i'm not clued into the GPS side of things (other than to understand the satilite side of things with it) but I was wondering, is it a device that can be used to store your home address details in? if so, I recieved an email a couple of months back about taking safety precautions with such things because they were being stolen and used to track the home address of its owner, one poor lady had hers stolen and within a short time of it being stolen and her returning home the perpetrators had cleaned her home out.
