I still do not understand what you mean by "datapages". Garmin does not use such term anywhere, as far as I know. If you refer to something from Polar, you'll have to explain what exactly in Garmin Connect you need to edit.

• I want to put Watt in left corner of watch, speed in right corner an so on…i  have looked in app and pc but cannot find it.

If you mean the customization of Data Screen on the watch, then you can do it directly on the watch. After selecting the desired activity, long-press the menu button, select Data Screens, and then adjust them as needed. Some watches allow editing the Data Screens also through the app, but mostly only newer models. I have no idea whether the FR945 allows it, but if you tap on the symbol of the watch on the top of the app screen, you'll see whether it offers that possibility or not.

Aha that is it. But back to my questions then. How to do it in app and pc?

I Done it 10 years in app and pc on Polar. How to do it on Garmin ?
