Di2 Field — Edge Explore 2

Di2 Field shows your current Di2 (tested with RD-M8250-SGS 12-speed) rear gear (e.g. 5•12) and the wireless unit battery level right on your Edge data screen. It connects over Bluetooth Low Energy — no ANT+ needed. GETTING CONNECTED There is no button to press — it's a data field. Connection is automatic: 1. Add the Di2 field to a data screen on your Edge. 2. Wake your Di2 by tapping any shifter (it sleeps when idle and stays invisible on the air until then). 3. The field finds the nearest Di2 and connects on its own — the status dot turns green and the gear numbers appear. 4. It then sticks to that Di2 (the dot turns dark blue) and reconnects to the same one automatically on every future ride. If the link drops, the field keeps retrying on its own and reconnects as soon as the Di2 is awake again — for a short break there's nothing to do. If the Di2 has been asleep for a long time it stops broadcasting entirely (a Shimano power-saving behaviour); when that happens the hint changes to "Hold Di2 button" — put the unit back into pairing mode once and the field reconnects. The status dot next to "Di2" is color-coded: - Blue — searching for a Di2 (pulsing while it scans) - Yellow — connecting - Green — connected and receiving data - Dark blue — connected to your paired Di2 (the one it locked onto) - Orange — link lost, retrying SETTING UP YOUR DRIVETRAIN For correct gears and ratios, tell the field your gearing — two ways: - Preset (easiest): pick a built-in Shimano preset for the chainrings and the cassette (e.g. 50-34, 11-34, 10-51). It sets your gearing in one tap. - Manual: set the preset to Custom, then choose the chainring count (1–3) and cassette size and enter the teeth of each ring and cog (comma-separated, one value per gear, from smallest to largest). While a preset is selected it takes over the chainring count and teeth — the manual fields keep their own values and are used only when the preset is Custom. Note: the settings screen won't copy a preset's numbers into those fields, and the prompt under each setting may not show on iOS — that's a Garmin Connect display limitation, not a problem with your setup. SWITCHING OR FORGETTING A DI2 Riding a different bike, or want to pair with another unit? 1. Open the field settings in Garmin Connect Mobile. 2. Turn on "Forget paired Di2" and save. 3. The field drops the current unit and locks onto the nearest awake Di2 on the next scan. The toggle switches itself back off — it's a one-shot button. To pick a specific Di2 when two are nearby: bring your Edge close to the right bike (or keep the other Di2 asleep), then use Forget — it grabs the nearest one that's awake. FEATURES - Large, clear rear gear with cassette size (current • total) - Front chainring indicator - Rear gear as numbers, a cassette graphic, or both - Built-in Shimano presets for popular chainrings and cassettes (10/11/12-speed), or enter your own teeth for any drivetrain - Battery percentage or a color-coded battery icon - Color-coded connection status dot with auto-reconnect - Automatic Di2 model detection - On-screen diagnostics overlay to help troubleshoot connection - Day / night color theme - Six languages: English, French, Spanish, Russian, German, Arabic RECORDS TO YOUR ACTIVITY (Connect IQ data in Garmin Connect) - Per-second: rear & front gear, rear & front teeth, gear ratio, battery - Ride summary: average & maximum gear ratio, front & rear shift counts, most-used gear combo with time share, top-3 most-used rear sprockets, highest rear gear used, lowest battery - Viewable in the Connect IQ section of the activity and any FIT-aware service REQUIREMENTS - Shimano Di2 advertising over BLE. Confirmed on Shimano XT Di2 RD-M8250-SGS (12-speed) with Garmin Edge Explore 2. Other Di2 series that broadcast the same BLE data may also work — the field detects the model, and the diagnostics overlay helps add support for new ones. Independent, unofficial app — not affiliated with or endorsed by Shimano.

v.0.34 Faster setup and broader Di2 support. - Drivetrain presets: pick a common Shimano chainring or cassette setup (e.g. 50-34, 11-34, 10-51) instead of typing every tooth count. While a preset is selected it sets your gearing; choose Custom to enter values by hand. - Automatic Di2 model detection, with the groundwork to support more Di2 series beyond the tested XT M8250. - New full-screen diagnostics mode (a setting): shows connection state, signal, the detected model and the raw data — turn it on and send a photo if a connection issue comes up. v.0.28 New display options and a clearer readout. You can now show the rear gear as numbers, as a cassette graphic, or both: the graphic draws every sprocket as a bar — largest on the left, height following the cog sizes — with your current sprocket highlighted, so you can read your position at a glance. The battery can be shown as a percentage, a colour-coded battery icon, or both; the icon fills with the charge and turns orange below 40% and red below 15%. The battery icon and cassette graphic are now on by default, and the settings option labels are fully translated in all six languages. Plus faster, more efficient Bluetooth handling under the hood. v.0.24 More reliable connection. The field now keeps its Bluetooth bond between rides and reconnects to your Di2 on its own as soon as it's awake — no re-pairing after a short break. Sticky-lock is more dependable: it confirms it's really your unit before locking on, instead of jumping to another nearby Di2. While linking, a seconds counter shows progress, and after a long search the hint reminds you to hold the Di2 button (a Di2 left asleep for a long time stops broadcasting and must be re-paired — a Shimano limitation). v0.0.16 Smarter connection: the field now shows what it's doing while linking up (Searching / Connecting) and reminds you to wake the Di2. It pairs with your own Di2 and reconnects to it automatically; a new "Forget paired Di2" switch lets you move to another bike. Connection status is now a color-coded dot (blue searching, yellow connecting, green connected, dark blue your paired Di2, orange reconnecting), and its alignment is fixed across all layouts.
