I recently switched from Apple WU to Garmin FR970 for two main reasons. Battery life for Gps Activity and Gpx navigation especially for trail running courses.. It's the latest model but it seems like it's very laggy, I understand it's a detailed map, but I missed 2 turns on my last run and that's a deal breaker for me.. It might be okay for walk / hike, but not for running.. Is there a way to make it responsive? I don't need to see street names etc.. I tried to make map details in low setting but I don't know what else to do.. It's working smooth in other brand's more affordable models...
