Two 999i's in the past week have frozen on countdown screen

Will not begin countdown to start up. Anybody else have this problem? Thanks


  • I just experienced it with a GM-80xt. Brought it home and went through all the troubleshooting I could think of and then found even though it had new batteries the voltage being supplied at the contacts was low. I retested each battery individually and put them back in and it was back to 12 volts. Countdown has returned. Now I can't get the firmware to update.

  • sent them both back and received S50i's in return. One only worked 3 days and sent it back too.
