A few months ago, a gentleman stopped by my house to ask me if I could direct him to another home in our subdivision. Our subdivision has been on Google Maps for about two years or so, and I was curious why he didn’t just update the maps on his vehicle’s navigation unit. Then it kind of dawned on me that maybe he didn’t know how to do it. Then it occurred to me that people may not even know that they can update the maps on their in-dash navigation units! This article is specific to the Alpine INE-W940, but other non-internet connected navigation units should follow a similar process. So let’s get to it and learn how to update maps on the Alpine INE-W940 Navigation Unit.
