I just want to thank you all again, and especially you Anne for your help in tracking the package. It is wonderful to work with people like you, for whom it is of no consequence whether one buys a simple cable or an expensive GPS. Your effort is the same in all cases. Keep up this way of doing business, it is refreshing.
