So bought the other half an upgrade for her bike. Basically changing over from 6700 to 6870 Di2 (I wanted the 6700 kit to sell an old frame off so seemed like a good idea!)

Given it's a slightly older TCR frame the cables are external. Shifters and derailleurs are 6870, the external kit and Junction A are from the earlier 6770 release side of things.

All plugged in and battery attached... Nada (with the exception of a green light on the Junction A when I plug the battery cable into the junction B.

Any suggestions guys and girls?

Cheers!

Have you tried upgrading the firmware?

Not sure that an older junction box will work with the newer kit. Perhaps you should get the 6870 junction box...?

It will work with older junction box. You need to make sure that firmware is same in all components ie. you need to plug it in computer.

Just be careful following the instructions: in some systems, drivers may get corrupted if you have the device connected while installing the software
