You can download the latest formal release of Maps Suite 2.0 by simply going into Software update on your phone. Please note that the installation is a big one, because of the sheer number of modules and possible system configurations supported.
You also need up to 40MB of free space on disk C: is needed, of which you'll get just over half of this back after installation. If you attempt to install Maps Suite 2.0 with less than 40MB free then you'll hit an error.
Along the same lines, note that it may help to manually remove all the components of previous Maps Suite installations in Settings>Installations etc.
Note also that this formal release does away with the myriad components in this dialog - in fact, Maps Suite 2.0 doesn't even appear in the main Installations dialog - it's effectively considered to be an update to the Maps subsystem that's part of the Symbian OS.
Much of the functionality will be familiar from our previous coverage, but here's a representative screenshot selection - now that Maps Suite 2.0 is formally available, it becomes an automatic recommended upgrade, so you can try it for yourself!
