Hi to all,
here I am again after a year, with the same problem. Unfortunately I accepted the fw upgrade to 27.13 version, and there serious faults in the Garmin-Sram communication are back:
- Indicated gearing continuosly swap between the correct one and the 34-32 combination (which is the shortest one)
- Annoying beep every 10 seconds (but it can be turned off in the settings)
- Sometimes, after powering up the Edge, the rear stop to work! I have to remove the battery, reinsert it and than the derailleur start to work again.
I understand that this bug will never be fixed by the Garmin/Sram support, so again I'm asking how to downgrade to 20.19 fw version, which was the latest working withe the A2 derailleur.
Thanks,
Stefano
