Which units this covers, and how to tell yours is one of them
Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Model — Forerunner 965 (running/triathlon)
- A top running/triathlon watch with an AMOLED display, full maps, multi-band GPS and training-focused metrics. NO microphone/speaker and NO phone cellular, so those symptoms do not apply.
- Training focus
- Its strength is running/multisport analytics (training load, recovery, race predictor). A GPS-distance question is usually satellite lock/mode, not the watch — wait for a lock and use multi-band in tricky areas.
- Battery
- Long for a running watch, but AMOLED always-on plus multi-band GPS shortens it — expected in those modes.

Questions that only have an answer for the Garmin Forerunner 965
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
My Garmin Forerunner 965 GPS distance is off on runs.+
Start with satellite lock: wait outdoors until it confirms a full GPS fix before you begin, since starting on a partial fix distorts the first part. In cities or under tree cover, enable the multi-band/all-systems GPS mode for better accuracy (it uses more battery). Sync the watch regularly so its satellite-prediction data stays fresh for faster, sharper locks. It has no cellular or speaker, so those are not factors.
Structured depth, not empty permutations
Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.
Device and manufacturer hubs share a consistent record system, but each answer carries the relevant controls, fault boundaries, consequences and official support entry point for that platform.
