I'm using an iPhone XS. It claimed it paired and then lost the BT connection while updating. Now, the iphone swears it's connected and paired but the gizmo wants to 
-pair and the phone refuses. I've told the phone to forget and start over, even rebooted the phone but both units are being stubborn. I'm going to retry tonight.

I have a 2014 Ultegra 11-speed Di2 system. It was the first to have hydraulic brakes. Is it too old to use this? I know the levers don't have the hidden buttons. Also, I have a 46/30T crank. Will the gear numbering get screwed up, or does it allow input with non-Ultegra chainrings?
Also, early on I heard it caused significant battery drain, but in another thread several people said that was false, or at least no longer is the case. Any issue?

My bike shop wired it inside the stem so it's no more than a couple inches away from my computer. They were very hesitant to put it anywhere further than the handlebars given the low power of the wireless signal it uses.
So far, it has worked like a charm. Definitely a "nice to have" but really do love the added functionality.

Most bike shops don't push DI 2 because they won't make much money off of it in the long run. There is no yearly tune up or maintenance because it just always works perfectly. If you are having problems with it take it to a good shop and have it fixed once and be done with it. Ask anyone who owns it and you will hear the truth.
