Just wondering when the update for the 2020 Sierra will be available ? Is it the same that the 2019 ? It looks the same for the wiring but not sure for the firmware.

There is a slight change in 2020. Firmware is in testing phase and will be out soon.

Thanks !!
Hi! I saw on the installing guide of the 2019 Sierra 1500 , that now it's written 2019-2020 and that 70.40 firmware should be used, but on the Flashlink Manager only the 70.39 is available for now... mistake or just because the firmware is not ready yet?

Thanks, just to give an answer to my customer
Choose "View other firmwares", 70.40 is there.
Thats what I did, it wasnt there the other day, Ill recheck anyway.


thanks !!
Note, latest firmwares are only available on modules with a QR code.
