I just completed an 1100 mile trip in my CS, mostly on back roads. The mapping and the algorithm for routing is the best I have ever used on an OEM NAV system. The satellite view is very handy when at 0.5 mile or greater scale and the system did not take long to find the best routing on good roads. It never put me on a dirt road and never had me make a wrong turn. I was impressed when compared with some other systems. I admit, the system is not as intuitive as it could be but for simple destination and route selection it is user friendly.
