Had the same issue. The SC reset the DAS (not sure what that is) which helped alot. They claimed the interior camera also needed to be replaced. I had them do that at another visit but it didn't seem to change anything. Its much better now, but it will still be off by 10-20ft sometimes. Way better than a 100-200ft off though.
 
Mine was off by a few hundred feet for a week or so and hard resetting (cutting power for 10 minutes) fixed it. Was back to working great the past few months, but yesterday was back to being way off for about a 45 minute drive. Today was working perfectly again.
