Recently bought 2011 Edge and have Samsung Brightside phone.  I get it connected to sync bluetooth just fine and it works great... for a couple of days.  After a few days it won't connect to phone.  All I can figure to do is delete the phone and then add it back in again.  It works for a few days then rinse repeat.  Any ideas why it won't stay connected?  I checked and software is up to date on both phone and car.
