Poor tire and Nagivation Problems
 The typical Goodyear Integrity tires are very poor under wet and light snow conditions.  My research at Tire Rack confirms my experience.  I have decided to install Michelin Primacy MXV4s to increase the safety of driving under all conditions in eastern KS.  The navigation suddenly lost its Bluetooth functions on the NAV system screen, no telephone icon anymore.
