I've been an extremely satisfied VMSpc user for three or four years now. When I begin my season's travels (We're on the road 5 to 6 months per year) I always start an odometer in the upper left corner of my gauges to keep track of the entire trip. It never gets reset. This year's trip began on June 1, and, about 4 or 5 days ago, this total trip odometer gauge lost all data except total miles, which continue to ratchet up with each mile driven. All other components are set at 0 and don't change. What happened? I really miss the cumulative MPG especially. I've always been able to see how the entire trip is tracking. Thanks for any tips.
