If you're satisfied with how it's working, IMHO you should leave it alone.
IIRC from reading the Syncmyride.com Owner-to-Owner forums, the GEN 2 (which I think is what you have) updates have been 'sketchy'.
If you're willing to do the research, you could verify your installed version and then peruse the forums to see if there are issues with any available updates.

I had a TSB on the Sync mic a few months ago and they installed the most recient version of the Sync software. The new microphone made a world of difference, however, all Ive noticed in the software update was the text on the display seems to be slightly different.
