Tom Tom Gps

I believe most GPS maps are made by NAVTEQ. The basic maps or the data that creates the maps is the same with most GPS. I do not know TomTom but if they use NAVTEQ and did recent updates they should be the same. But it is what the device makers do with their programming to make the maps work in their device that may differ. I am not sure about TomTom as I have never seen one. We use both MS Streets & Trips in our laptop and a Garmin device - they both use NAVTEQ but the appearance on the screen is different. Not sure if I am making sense - trying to keep it simple. Electronic maps are sort of a series (a huge series) of Lat Lon points which are sort of strung together - this is the data. The maps are pictures created by using the data. There are all kinds of technical ways to explain all of this but I am not the one to do it. Best to keep it simple so everyone can get some idea of the basics of how it works. More information can be layered over the base to show specific spots on the map - points of interest - waypoints - this is the difference between the device makers. Check your TomTom to see where they get their maps - then use the TomTom to go to specific places and streets you know of on their map to see if it looks current. The most recent and obvious additions to Mexico maps would be things like the Devil's Backbone and Arco Norte which just opened last year and are new on the most recent Garmin updates. If they show up on TomTom then you could be OK. Devil's Backbone runs between Mazatlan and Durango - the old road is 40 and the new road is 40D and runs sort of parallel - if your map has both roads it is pretty much up to date.
