Can't select all XM radio channels while driving
Bought 2007 FWD Torrent with Nav Display and XM radio a couple of weeks ago. When you display on the map screen the XM categories and channels associated with those channels, you cannot scroll up or down in the list of either categories or channels while you are driving. As soon as you come to a stop, the buttons on the left, to scroll through categories, and the right, to scroll through channels light up again and are selectable. But as soon as you start moving, the buttons to scroll either categories or channels are dim and not selectable. Anyone know about this problem?
