Anyways ... Eicher publishes a perfectly good national road map of India,
regional road maps, and also do street directories of the five major
cities. Widely available in bookstores.

I guess the OP declined the street directories as useless. In which scale
this national road map comes? Knowing that the geographic size of India is
around 3.3 million square kilometres, the street atlas supposedly comes with
at least ten thousand sheets. Otherwise it can be described as "perfect" but
hardly as "detailed". Digital maps come to rescue. What about google m.....?
