I recently bought mapmyindia navigator (paid 18k) in pune. This is utter useless product. It has no right maps, no correct roads, doesnt know "no entry", asks you to take right when there is a divider.. Frustrating experience in pune, panvel, belgaum. If you intend to buy, have a trial using my navigator (Im not using it anymore - junk product).
Its costly, instead try nokia gps. One of my friend laughed at me when his nokia phone showed the right route and this gps was fooling around.
