On UT+ firmware update. I don't think it is possible to update the
firmware in a UT+.
Back in 2006, time-nuts had a member, Randy Warner, who worked at
Synergy. In the message linked here
He describes the firmware update as a factory-only process that could be
done then for $25. Now I doubt there is any way to get it done. I have
never heard of any way to accomplish it without unobtanium factory tools
If you search in that mail-archive time-nuts section (linked above), for
the subject "Oncore GPS models", you may find some more information.
