Do you have any instructions or a "how-to"? 
The polar align feature sound like a great idea.

before you upgrade, you should check to make sure what version you have-if its a new scope you may already have v 4.15 or 4.16 (4.15 has bugs for the southern hemisphere)
if you have an older version-but a flash upgradable hand controller- you can download the latest version of the hand controller and motor controller firmware from Celestron
http://www.celestron.com/c3/downloads.php?Products[]=57&Submit=Search
you are after the handcontrol firmware update
once you have downloaded the update, you have to connect to the mount using the serial cable , and then the software guides you through how to install an update. Its fairly straightforward-you hold down two buttons-cant remember which two, but the software will tell you-and cycle power and that puts the HC in the mode to receive data
you can while you are at it update your Motor Control firmware as well-I am not sure what benefit it provides but I did it anyway
You can download and check out the software without being connected to the mount just to see how it all works
Manuals (pdf) are also available at this location
Here are the release notes from the Celestron site which explain it all
