Coros has added offline maps to the Coros Pace 4 through a free software update, according to Tom’s Guide. The change lets users download map areas to the watch and use them during outdoor activities, including when following routes with turn-by-turn directions. The update addresses one of the main omissions Tom’s Guide identified after several months of using the Pace 4 for marathon training. The outlet frames the addition as notable because offline maps are more commonly associated with sports watches that have more onboard storage and often sit higher in the product stack. The catch is storage. Tom’s Guide reports that the Pace 4 has 4GB of onboard storage, while watches with mapping features more often start at 16GB. Some of the Pace 4’s capacity is already used by system data; the reviewer said their watch had 1.6GB free with no music stored on it. That does not make the feature unusable, based on Tom’s Guide’s testing. The outlet says users should still have enough space for local maps and regularly visited areas, but not for downloading the whole world. It gave two examples from the Coros app: two areas covering London and the south east of the U.K. totaled 151.2MB, while two large areas covering New York and Philadelphia totaled 122.4MB. The storage trade-off matters most for users who also keep music on the watch. Tom’s Guide notes that those users may need to remove tracks to make room for map areas. The practical workflow is therefore closer to trip-by-trip map management than a set-and-forget global map library. Setup runs through the Coros app, according to the report. Users update the watch in the app, then choose map areas from preset squares rather than downloading by country or city boundary. The app shows the file size for each selected area, and the watch downloads the map data over Wi-Fi. Once maps are installed, Tom’s Guide says they can be viewed during outdoor activities by using the Pace 4’s action button to switch between workout stats and the map view. Routes can be created in the Coros app’s Explore tab and synced to the watch. The outlet also says the Pace 4’s AMOLED display is bright enough to make maps and routes readable despite the watch’s relatively small screen. Who benefits: Current Pace 4 owners gain a new navigation feature without buying a new watch. Prospective buyers who want basic offline route support on a lower-cost sports watch also get a stronger case for considering the device. Who's exposed: Users who depend heavily on onboard music and maps are the most constrained by the 4GB storage ceiling. Anyone expecting a full global offline map library on the watch will need to manage downloads manually.
