Shimano needs to figure the installation out better than this...
Once it’s working... it’s great. I thought the online descriptions of these units bricking di2 systems was a minority, but I also had he update bricking and I don’t have easy access to a windows PC (if you do - you are better off). Anyway, after disconnecting, reconnecting all the components from the system, getting an iPhone to connect after my iPad wouldn’t anymore, it finally started working again. Took way too long to get working. Why should have taken no more than 5 min took almost an hour !
But it’s all paid off after it finally started working again (I have no idea what worked, so I will go through it again when I install the next one on my other bike). Yes, even after all this difficulty, the value of using my phone and connecting to my head unit outweighed the pain to set up !
