I use GPS quite a lot. And i'd say in Bangalore, i have almost no complaints. But I've noticed Google Map to be way more accurate. If you have a unlimited data plan, like i bought a weekly unlimited plan from airtel, you could use GoogleMaps for very accurate navigation. It has almost all of india digitized in maps that can be used with the integrated GPS.
You could also opt to buy maps from MAPMYINDIA, which claims to have throughly mapped India. But check it out before you buy it.
I hope this helps.
