Wisdom 2 firmware?

Hi. I am about to leave for a liveaboard with a friend that has a Sherwood Wisdom 2 dive computer she bought a couple of years ago. Are there firmware updates released, or are they just set at the factory never to be tweaked? I looked on Sherwood's web pages and did not find any listing of firmware versions, etc.

If there are updates to the firmware, can the consummer performt he upgrade, or does the update have to be made by a registered dealer or the factory?

Thanks.

Fastest with the most accurate info would be calling sherwood. I have the wisdom2 that I keep for a spare and would be interested in the answer to this as well. Please post once you find out... lee
