When people submit reviews on the diverse GPS devices from the larger brands, they appear to focus primarily on the the device itself; the appearance, performance levels, and the user-friendliness of the unit. What those reviews normally ignore, regrettably, is the GPS Software which is required in order for the device to interface with the Windows or Mac systems correctly. This software is needed for functions like synchronizing and downloading the most recent maps and POI’s to a GPS device. Similar to regular software, GPS software that is too hard to update should be avoided. Knowing about the differences between GPS software may not be the point that moves you to purchase one given brand, but knowing about the supporting software is important after you already put money down on one GPS device. The kinds of GPS software are going to often be practically identical for the range of models within a specific brand. A nice model to look into is the Garmin Nuvi 465t Truck GPS Navigator.
