I have used a Garmin for well over two years - first a 265WT with SatGuide maps, and now a 2465LM with Navteq. Now I have got very used to it. In fact I was visiting someone in South Kanpur yesterday. I took my Garmin just to save his location so that I can navigate to his house using unfamiliar routes (esp NH2 Kanpur bypass). At the moment I know of only one passable route.
I have a query, what kind of back up can we expect from these navigators. Also why did you switch to other navigator, did the first one get kaput.
