Sram's website state that my Garmin 520 will update the software automatically, which will allow me to see the SRAM etap options in my 520 device. However, I am not able to see the E-Tap battery option.
Garmin will only show DI2 battery life.
Has anyone been able to resolve this issue? I am trying to allow for my Garmin to show me the battery life for both front and rear derraileurs
