The guy said the map is updated, Apr 2010 version, and not the Free map. He said the updated map is far better than the Free map (which according to him doesn't even include the elevated u-turn in c-5 and the c-5 extension). He also said higher models have features which are not applicable here like Traffic monitor and Lane Assist (i don't know what are these)

Anyway, i'll think about it yet.

Thanks for the advise.
