The Cockpit view from a Cessna Citation 550 corporate jet as we fly around weather. We use weather radar and a GNS 530 with XM Satellite and WX Weather Service to avoid the cells.  This combination is the best way to go. I like to think of the Garmin as my strategic display for weather planning and the weather radar as my tactical display for maneuvering around cells. At our destination we have to fly around some cells and get into a little rain just before landing.
