Hi There 
Can anyone help me i've just bought a gm 120 speedo (2010) with 12.4 firmware on it and want to upgrade it to 13.1  I dont have any gm software at the mo on my computer we tried it on a friends computer who is also running a gm and it would not allow us to change it? Any ideas on what to do?
 
Also where is the best place to download the Firmware? 
 
Many thanks

All the software / stuff you need is on there.  There is a difference in the "reset" procedure prior to firmware update depending on the age of the speedo - it's described in one of the pdf's that comes with the firmware.
