Just to update this thread, I've been using MMI V6 for 3 months or so, though a lot of roads are updated some main roads are sorely missed. I do my travel between Bangalore and Pune among other places and one section of NH4 near Haveri or so goes missing, its basically the by-pass that are not correctly updated. In-city its right there, almost perfect, some imperfections you can live with, else between the 2 states its currently the best map available out there.

Hope others update their experience too.
