This is a shocking discovery I made after purchasing these for my wife and I. Since 2015 we have used a range of watches from Motorola, Samsung and Fitbit. Whilst they did not have GPS built in, the phone does and every single one has shown a map when you run with your phone. How have we made it to 2020 and Garmin cannot get 6 year old software and tech right? Clearly this is a commercially driven decision to restrict the watch / app.
When we bought the watches we were led to believe they would use "GPS Connect" which uses your phones GPS. The app previews also show a Map in the Play/Apple store without any disclaimers.
Even messaging your support staff, they believe @GPS Connect' should work.
Garmin, This is the kind of stuff that annoys people not builds trust or faith in a brand. It would take minimal effort to resolve.
