We purchased the Navigon 2000 GPS system November 2008. Since then we have used it in our Motorhome and car for well over 20,000 miles. It has NEVER steered us wrong, even when we thought we knew better and went a different road, she re-calibrated route and helped us get where we were going. This is a very easy to use navigation system, with upgrades on the internet. We had 3 'other' systems in the past 4 years, and the Navigon is the most superior.
