Hello, i recently upgraded to Shimano DI2 12V with my Edge 520 plus with latest Garmin firmware 5.70 but when adding on the data screen the DI2 Gear Battery y just get a question mark instead of the battery level of the shift levers and the DI2 Battery level as supposed, any idea?.
Also the 11-34T rear gears preset are not accurate, the correct gear set is 11-12-13-14-15-17-19-21-24-27-30-34T but the included is not accurate.
