If you're satisifed with the performance of your AN!x then there is 
no need to upgrade.

Hold the keys '0', '-', and '+' while powering on the AN1. The OS 
version will display following the welcome messages. Be aware 
that you have now entered 'test mode' and this is undocumented 
in the user reference manuals - I couldn't tell you what may/may 
not happen if you decide to play around with the setting while in 
test mode.

The last AN1x OS update was v1.04 which had some minor bug 
fixes. There are some support docs on the update in the Files 
section for this mailing list at Yahoo! Groups 
http://groups.yahoo.com/group/AN1x-list/files I *think* someone 
even uploaded some JPEGs from the interior of the AN1x.

It's been awhile since the OS update has been discussed on list 
- I'm uncertain what fee's, if any, apply to the update EPROM from 
Yamaha. I would recommend you inquire of YCA from the 
http://www.yamaha.com/ web site. It usually takes 24 hours for 
them to get back to you. Be aware that their policies may differ in 
the CONUS from the ROTW
