Garmin Instinct 2 Solar
D2 Cloud-Optional — Full function with the router off.
The unplug test
The Instinct 2 Solar tracks GPS activities, records your runs and hikes, shows heart rate and stats on its own screen, and charges itself from sunlight with no phone, no Wi-Fi, and no Garmin Connect account ever created -- the owner's manual explicitly describes phone pairing during setup as something you 'can' do, not something required. Skip the app entirely and the watch still tells time, navigates, and logs activities to its own memory. What you lose without Garmin Connect is smartphone notifications, Connect IQ apps and watch faces, syncing activity history off the watch for long-term storage and analysis, and features that depend on a paired phone like LiveTrack safety tracking.
Why this tier: Garmin operates a real, named cloud service for this watch (Garmin Connect), so D1 (no vendor cloud at all) does not apply. But the watch's own Owner's Manual states initial setup does not require pairing: 'During the initial setup, you can pair your smartphone with your watch to receive notifications, sync your activities, and more' -- 'can', not 'must'. The manual's Phone Connectivity Features section describes pairing as something that additionally 'unlocks' notifications, Connect IQ apps, Glances, and safety/tracking features, without stating that GPS tracking, activity recording, or the watch's core timekeeping/navigation functions require it. Core function (GPS satellite navigation, activity recording, on-watch stats, solar-assisted battery) runs entirely on the watch. Vendor cloud exists, setup completes with no account, and core function works unconnected -- the D2 row.

Where to buy
Open questions
- The exact FCC ID covering the Instinct 2 Solar (M/N A04094/A04095) was not found within budget -- searches for the model numbers directly returned no match on fccid.io, and the two grants found under Garmin's IPH grantee code that mention 'smartwatch' correspond to other models (Instinct Crossover, and an unspecified 2020 filing). radios and local_api are left including 'unknown' pending a firmer FCC identification, though the manual independently confirms Bluetooth and ANT+ via trademark/certification pages.
- Whether firmware updates can be declined, and whether they are pushed automatically once paired, was not established within budget.
- phones_home and repairability were not directly documented within budget.

Full Instinct 2 Solar One Piece Owner's Manual (confirms this manual covers model M/N: A04094, A04095, i.e. Instinct 2 Solar specifically). Legal/trademark page confirms Bluetooth and ANT+ certification; last page shows ANT+, Bluetooth, and MCMC (Malaysia) regulatory logos. Table of contents confirms full activity tracking, training, history, and navigation feature set is documented as on-watch functionality, separate from the later 'Connect IQ' / phone-linked sections. — accessed 2026-09-03 - A https://fccid.io/IPH04348
Confirms Garmin International Inc (grantee IPH) files FCC intentional-radiator grants for its watches (this particular grant, filed 2022-10-04, covers a Garmin 'Hybrid Smartwatch' with BLE 2402-2480 MHz and 13.56 MHz NFC) -- establishes IPH is a grantee that files for radio-equipped watches, though the exact grant ID matching Instinct 2 Solar specifically was not pinned down within budget. — accessed 2026-09-03
