When my 2013 GT500 was in for a service/oil change AND a SYNC software update, it appears the "Track Apps" option has literally disappeared from the menu in the "Gauge Mode" in the information display. :fm: Has anyone seen or heard of this happening? I'm at a loss to explain how this is even possible. Any thoughts? I know I can take it back to the dealership, but can that be avoided ?? Thanks for any input.
