I'm running the 2.1 leak and set a destination to a store about 20 miles away...set the Eris on the dash as I always do. Half way thru the GPS quit working. My wife couldn't get to work . I pulled off and pushed the navigation icon and finally got it to work again..then it quit again 2 minutes later. Any Ideas or suggestions on why and how to fix is greatly appreciated. If this is a bug in 2.1 leak , I hope it gets fixed before this gets rolled out to all those biting at the bit.
