Has anybody installed it? Is it worth installing?
And what on earth is Smart Mount?

Autostar II version 4.0h (1,826 KB) is available for LX200GPS telescopes. To get the new version, use either the 4.0h link and download and unzip the file to the Ephemerides directory under the Autostar Update (ASU) installation directory or use ASU and press "Upgrade Autostar Software Now" and ASU will download the file and upgrade the handbox. If you don't already have ASU use the link on this page to download and install it on your PC. This version is to be used by all LX200 GPS telescopes. It will not affect your Smart Mount status. If you have Smart Mount, you will still have Smart Mount with this version. If you have not paid for Smart Mount, you can still use this version, but it will not have the Smart Mount function.

NOTE: Only the RS232 port next to the HBX port can be used for upgrading the handbox.
