Garmin Connect UK Roundabouts

Former Member over 9 years ago

Hi,
I'm fairly new to Garmin and the Garmin Connect framework.
So I've created a couple of courses, been on some rides, all fine.

So now I get creative and create some longer courses. What I've noticed is that sometimes the algorithm that creates the route is trying to take me the wrong way around (large, busy!) roundabouts (to the right). Sometimes it gets it correct and takes me to the left.

I think it may have something to do with trying to find the shortest route. So if at the roundabout the route is to the right it will take you the wrong side of the roundabout. If the route is to the left it will get it right.

Is this a known issue? There is another thread on here where this has been discussed (about three years ago) and no resolution seems to have been forthcoming.

For now I just have to be careful, check the route and put a waypoint in to take me the correct way.

It may be because for North Americans a roundabout is a completely alien concept :) !

PS I've just checked on Strava, it seems to have exactly the same issue, be careful out there!

I was having the same problem. Did a few tests and it does seem to be a shortest route thing.

And the USA does have roundabouts. About 3500 of them. Sounds a lot but when you consider Basingstoke alone has over 250 then yeah, not really surprising that they don't support them.

That said, if you zoom in on Google Maps (in Garmin Connect) there are tiny arrows on the roundabouts that show direction, so that information is stored somewhere. And indeed Google's 'Directions from here' functionality correctly finds its way round roundabouts.

Would anyone really enter a roundabout and go round it the wrong way because their GPS device tells them to?

I agree it could perhaps do with fixing but use common sense and you should be safe.
