I have an question for the Euros out there, first off I have worked with GPS for the past 6 years, I would never order NAV built into a car. But the deal I got on my Challenger with it already there I'll take it. Here in the US there are various satellites making up the GPS constellation between 16/18 orbiting with 1-3 stationary WASS and if you can use the GLONASS system there is another 8-12 orbiting. Does the NAV even work in Europe? Because the stationary satellites for Europe are EGNOS and again there are 1-3 possible satellites. I am just curious about the map question as to does the NAV work but you can't see the roads and graphics.
