I mean, I know how they work, but is there a subscription to a service you have to get after the initial purchase of the GPS? I have given up on finding DH a extremely large Harley bar and shield for Christmas, so I was thinking about getting him a GPS unit instead. He's always wanted one, though Lord knows why. We never go anywhere to use one and he knows the streets he patrols like the back of his hand. I think he wants one because all the other boys have one. Anyhow, we are trying to cut back on expenses as we make plans for his retirement. I'm not going to get him a GPS if it means subscribing to a service and having another bill each month. Also, what would be a good one to get?
