We may not be building new VMS 200's, but we haven't forgotten our thousands of customers that are driving around with our all-time best seller. In fact, we have just released a new software version that is the biggest upgrade in that product in several years.

Version 4 adds two major new features, both born out of my personal experiences as an RVer. It also adds a few lesser, but still important, features, like making the MPG reading bigger on all the trip screens.

Although I absolutely love the "Rolling MPG" feature of all the VMS models, I recently realized that it is missing something. The Rolling MPG is perfect for fine-tuning your driving to get the best fuel economy, but it doesn't give you a very good idea of the "bigger picture". So I added "Recent MPG" - the MPG as experienced over roughly the last 10+ minutes. It gives a better idea of how the winds and hills are going to hit your pocketbook at the next fuel stop. Both are available as gauges for your Drive screen and your Scan screen.

Another idea came to me as I was crossing the country on a month-long trip. I clear my Main trip only at the beginning of a totally new expedition, or at each end of a cross-country jaunt. I clear my Aux trip screen when I refuel, so that's my fuel gauge. But on that long trip, every day I found myself curious about just how well I was doing that particular day. So I invented the "Daily Data" screen. It's a trip odometer that clears itself automatically each morning so you can easily see how you are doing each day. It only clears once each day, so when you stop for lunch it doesn't forget your morning's achievements.

If you like these features as much as I do, then check in with us at the next rally and we'll update your unit for just 95 bucks. If you can't get to a rally, you can send your unit in to us and we'll update it in the lab for the same price.
