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.

Model numbers and patterns: 42/47mm
What that covers: Garmin watch; AMOLED/solar display, maps, music, multisport sensors and charging contacts vary.

Published specification

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 — Approach S70 (golf): A golf-focused watch with an AMOLED display and preloaded course maps (yardages, greens, hazards) plus general health/fitness tracking. No microphone/speaker and no cellular, so those symptoms do not apply.
Golf features & app: Its golf features rely on the Garmin Golf app and course updates; a course showing wrong data is usually an outdated course map — update courses via the app. It pairs with Approach club sensors.
Battery: AMOLED with good battery; golf rounds with GPS shorten it, which is expected.

Exact questions

Questions that only have an answer for the Garmin Approach S70

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 Approach S70 golf course data looks wrong.+

Course maps get updated as courses change, so wrong yardages or missing hazards usually mean the course map on your watch is out of date. Open the Garmin Golf app, sync the watch, and update the CourseView maps for that course. Make sure the watch has a solid GPS lock before you start the round. The S70 has no cellular or speaker, so those are not factors; it is a GPS-and-app device.

Structured depth, not empty permutations
