URGENT...GM120 2010 HELP
so i have been running V11.1 on my GM speedo for 3 months now, the night before a race meeting (tonight) i decided to update it to 12.2
So i followed the instructions and updated the same way i have done in the past... all installed successfully but on V12.2 it wont perform a factory reset or enter the set up mode, it just sits there the fan is pulsing slowly as is the light on the spektrum receiver and the speedo shows a red light.
If i back date it to V11.1 as before it does the same thing. I have a race meeting in ten hours so am extremely stressed out at the minute
Thanks in advance
