Edge 520 plus with Di2 12v Gear Battery ?

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.

  • I think the 520 has both a Gear Battery for ANT+ compliant systems and a Di2 Battery data field just for the Di2 system. Try the Di2 battery data field.

  • thanks for your help, that is the current info i'm using, but that is not presenting the different components battery levels, just one big percent battery consolidation, i will like to know what is the remainind battery for the CR2032 and the DI2 Battery. also i have seen this working on other garmin models, can it be enabled on mine? 

  • The 520 does not split the batteries out on the training pages. It might under the sensor details, but the Di2 12 speed came to market after the last Edge 520 update was released. There is a good chance the 520 does not support multiple battery information for the Di2 system. The Di2 uses a private ANT protocol. The changes to the protocol came out after the 520 software was released.
