Questions about Garmin Forerunner 45S

This is indeed a bad translation. We have changed the name, thank you for your intervention. An article has been written on this subject: https://www.digitec.ch/fr/page/haricots-gelifies-traductions-automatiques-sur-digitec-et-galaxus-8768

Without an account, I can't tell you for sure. But it probably doesn't work. In my case, however, the watch no longer finds a GPS after a while if it is not connected to the mobile phone. Furthermore, the time is no longer correct when the battery is empty for a day. The time is automatically transferred from the mobile phone and cannot be set on the watch. In terms of size, it will certainly fit.

Bluetooth can be switched off separately on the Forerunner 45 and the 45s. ANT+ is not available or not supported (I am not aware that the watch has this function).

No, there's no microphone.

No

By pressing the start button, you first select the sport you want to practise and then press the start button again. It is also possible to change the sport afterwards.

The watch has no integrated memory for this purpose. However, since it can be connected to the smartphone via Bluetooth, it is possible to control the playback of music. However, the mobile phone must of course be close by and the music is also played on it.

Yes, you can switch it off. Training should be possible, but I've never tested it. Great watch for the money, I can really recommend it.
