I think that there are no round elements in OSM nor in Garmin.

In order to display a roundabout there are several strait segments.

You seem to use a quite thin line to display your roads. I am using
bigger lines, so it is less evident to see the segments and optically
it displays smoother.

On the top (north) side of your roundabout appears a dent. I do not
know why, but I think that there are still much to many nodes to
describe this small roundabout.
