My question is what extra will this world map provide over basemap?

Is there chance that my basemap is more up to date and if i enable this map then i will see outdated info?
I certainly wasn't suggesting you replace your basemap with this map, quite the contrary in fact, so maybe you've misunderstood what I said before about how a worldwide basemap compares to this WorldMap. The map loaded as OEM to your GPSMAP62Sc is this map: [Only registered and activated users can see links. ] or possibly an earlier version depending on when it was produced. Same is also pre-loaded to the majority of Garmin units including auto devices. See my previous post for what this map is for. It's not intended for it to replace a basemap and in fact it can't. It's intended for it to supplement a basemap but not to the extent that a detail map does. Have a look at these explanations: [Only registered and activated users can see links. ] and catymag's other post here: [Only registered and activated users can see links. ].

This Version 5 of WorldMap was released in August 2010. Version 5.01 Basemap was released in March 2011. The basic data is probably the same [or very close], but the WorldMap will usually have additional info not present in the basemap. What that is is anybody's guess until you compare a given location or area. But at the very minimum the WorldMap will have basemap level detail at any given spot and almost certainly will have more than the basemap.
