How do I find out the version of a map? When I touch the screen in the bottom right I get the route summary, battery level, the icon showing the satellites & bluetooth. Below that it says version 9.430 with both the Europe map & the same when I switch to the North america map. I am not particularly concerned about the North America map anyway it was just that I was able to get the 930T for the same price as the 730 when i bought it.
