    If you have to ask, usually retail bikes do not include it.

    Get the unit and a short E-Tube cable as well. Wrap the unit in some foam (so it doesn’t make noise if it bangs around) plug to the seatpost battery and let the other cable and unit just dangle in the seat tube.

    And as warning, if connecting via BT and one of the apps, DO NOT DO AN UPGRADE of components. If you attempt to upgrade the BT unit via BT, it frequently crashes. Do the BT unit upgrade via a cable connected laptop using the Shimano E-Tube software. The crash is major and is to be avoided.

    Newbie Di2 user here with a stupid question....If everything is working the way I like it, is there any reason to upgrade the firmware at all? In the future I do plan on getting the WU111 unit also so I can have battery info on my garmin and I suspect I'll have to do it then.

    No. In fact there's more reason not to. As with any electronic/software device... new firmware sometimes screws things up. Or removes features. Google "di2 bricked" and you'll get lots of horror stories.

    If you do think you'll do it in the future, probably want to do it while still under warranty just to be safe.

    I've got 2 di2 bikes that are a few years old. Never updated them.

    There are unfortunately a number of posts here about why not to do this.

    What it sounds like has happened is the iPhone connected, then an automatic update of the Di2 wifi unit started. Now it's stuck with the Di2 wifi unit unable to finish the update as the BT connection was lost. Endless loop.

    I would attempt a cable connection with a laptop that has the E-Tube software, using the charging cable and see if you can re-start the WU111 update. If not you end up either taking to a LBS that has the Shimano SM-PCE1 cable and can re-install firmware, or you can buy that for about $150.

    Lesson is NEVER do updates with BT !.

    I would suggest updating with the SM-BCR2 charger directly connected to a laptop with the ETUBE software.

    It will update everything except the wireless unit, which I believe HAS to be upgraded using the IPAD/IPhone. Just do the wireless part last.

    If your computer doesn't recognize all of your components, try disconnecting everything completely for a few minutes, then plug the battery in directly to your A-Junction and update those to by themselves. Then reconnect everything and update. At least this is what worked for me...

    No Mac. Windows only for ETube.

    You might want to take a look at this site. There is some info here about the issues you experienced.

    That is exactly what happen when mine was updated the problem
    Now is that it does not respond it all. No lights on the junction box either.

    Unplug the battery. Let it sit. Okug it back in. The BCR2 should talk to it on PC

    DI2 battery levels are ridiculously easy to check. Press and hold one of the shift buttons that won't elicit a shift (ie press the down shift button for the FD when already in the small chainring) and check what the lights on the A junction tell you. You either get solid or flashing green or red lights. Green lights are good - red means the battery is getting low. Solid green means 75-100%, flashing green 50-75%, flashing red 25-50% and solid red means 0-25% charge.

    The battery lasts a long time. Charging once a month would be very conservative. I usually have to charge every two to three months after 5-8 hrs of road use per bike per week.

    I have heard of so many issues with the BT capability in DI2 that it seems like a completely unnecessary hassle if you only want it to check battery levels on your Garmin. I have always found it best to have a hard wire connection to the system to do any firmware updates or component diagnostics.

    You have your red indicators backwards.
    http://si.shimano.com/pdfs/um/UM-71J0A-001-00-ENG.pdf
    100% remaining: Illuminates green (for 2 seconds)
    50% remaining: Flashes green (5 times)
    25% remaining: Illuminates red (for 2 seconds)
    0% remaining: Flashes red (5 times)

    Yes it's easy to check the battery, but doesn't hurt to have an extra reminder on your garmin.


    What I find more useful though is if you're using syncro shift, your Garmin will beep and warn "Chainring shift next".


    The battery lasts a long time. Charging once a month would be very conservative. I usually have to charge every two to three months after 5-8 hrs of road use per bike per week.
    I'm still amazed at how much life out of such a small battery. I get about 1,000mi between charges and typically charge when it gets to red. I've never let it go to blinking red.
    Also this bike is mostly my winter bike. During the summer, it may go a few months without being ridden. I haven't noticed any drop in battery life by sitting for several months.

    Di2 (red) 1,088.4 mi
    Di2 (blinking green) 692.9 mi
    Di2 ?? 754.4 mi
    Di2 (red) 1,132.4mi
    Di2 (red) 883.6mi
    Di2 (red) 1,027.0mi
