There is apparently a way to update the Tbolt firmware.  Several years ago a Chinese seller of Tbolts was selling units that he upgraded the firmware from v2.xx to v3.xx     He may have pulled a new firmware chip and dumped the image and re-programmed the older ones externally or used JTAG,  but that seems like a lot of work for minimal gain.


> I'm aware (until now) that there is no firmware around and no firmware flashing tool for
these GPSes. Maybe the flashing tool(s) is(are) suitable for the
Thunderbolt too.
