Garmin City Navigator (2010) ($100 ~= INR4700): It is ok inside city limits. Most of the PoIs are up-to-date till last year (I think). It is the same map you get with Nokia Ovi maps (same vendor NAVTEQ). But go outskirts and all it draws blank. For example (someone borrowed my map) electronic city is just the main road, no internal details are available. Moreover it has a very annoying tagging bug, it marks even provision stores as fuel stations; so when you search for nearby petrol bunk the search results are polluted by grocery stores around.

MapMyIndia (4.01) (INR 7000): This is by far the best in terms of details. And I am sure 5.0 will do better. Still some data is outdated, but that is expected in ever changing Bangalore. The annoying bug here is what people have observed above, in map view mode it shows apartments as major landmarks; and I couldn't turn it off. So any area you browse, the screen is littered with apartment names (and small blue boxes showing their location), and there is high chance you'll touch one of them when you touch-scroll.

Satguide.in map (2010) (INR 1000): The cheapest of the lot; and you get what you pay for. Even being released 6/7 months ago, it insists on taking U-turns in Old Airport road in places they closed several years ago. To come to ORR it tries to take turn on roads where they have put a wall even before Airport shifted out to Devanahalli. The PoIs are similar to MMI; but there are lack of details too. Mapmyindia knows about service roads (for example in ORR) and advises you in right place to merge with main road, whereas Satguide didn't. And surprisingly, the apartment display bug is worse here, in addition to well known apartments, it also shows symbolic names as "A6", "J32" etc. Maybe MMI/Satguide tags apartments with some value that Garmin interprets as very important!

So details wise MMI is a clear winner, but Satguide is best VFM.

But anyone knows how to work around the above bugs?
