Which ones come with Swedish super models? Mine came with supermodels but not Swedish ones.

Wahoo would work. 530 would too.

Don’t know why you want to look at maps without using them for navigation.

The maps on the Garmins are more detailed. A touch screen makes it easier to pan/zoom the map.

Maps work better on a larger screen but the small ones should be ok.

The Roam costs as much as a 530 (I think) but the 530 is more powerful.
