Navigational (global Positioning System) Gps problems of the 2010 GMC Yukon

My dashboard has cracked and is now in many pieces. I know it is expensive to replace so I've glued and taped it together to the best of my ability. The dash rattles and shakes throughout any trip I take. I love my car! I want it to be �healed�. It's very distracting to drive with your dash making all that noise. If I'm ever in an accident, even ever so small, I'm sure parts of that dash will go flying and hurt the driver and/or passenger. I also don't know how safely contained my dash-airbag is. My speaker and gps are also on that dash and are no longer installed where they should be causing more problems in their new locations which could result in something else not functioning like it was designed to be. I take care of my vehicles with regular tuneups and replacements where needed. This is beyond my control and is a serious flaw in this vehicle.
