Navigation and roundabout

Thanks Wongataa so you are saying it's just a routing blip ? Like you say, there were clues and i'm not going to be riding my bike on the M25 because my Gamin suggests it !! It's funny that i didn't get the super zoom thing on the roundabout that has the routing error, though ?

It looks like a routing blip.  I don't get the superzoom issue at every junction.  Sometimes it is there and sometimes not.  I don't know what triggers it.

Thanks. Have you turned the 'Auto Zoom' setting to off ? I assume that you have tried this without success ? I think that the super zoom is just more confusing at a roundabout. If its a normal left or right turn i guess it looks the same even if super zoomed. The only difference is that the triangle showing your position would travel through the display very quickly. That wouldn't confuse me too much.

I can't remember if I have tried turning auto zoom off.  The issue is definitely worse at roundabouts as you say with a left or right turn zoom level doesn't matter so much.

I need to try this again at a big roundabout, now that i've turned auto zoom off. I just don't live that near to any that i would want to go to.

Hey all, there might be a possible explanation for your "rounding blip". It's probably not a "blip". So if you're using the "OpenFietsmap Lite" map from the site, it has a weird way that the routing is handled. From http://www.openfietsmap.nl : "automobile routing not supported: Routing with vehicle=car is meant for racing bikes"

So when you use this map, if you want to get correct navigational cues, you have to set the routing mode in your activity profile to "car". (Settings -> Activity Profiles -> "your profile -> Navigation -> Routing -> Routing Mode -> Automobile Driving).

If it is set to "Road Cycling" then it will be in sort of a permissive city riding mode, where it ignores the direction of one way streets for example. I think this is a pretty horrible decision from the creators of the map, and this bit me in the bottom twice, as when I switched back to the maps I created (or from other sites) then it was trying to bring me on highways.

Anyhow, give this option a try and see if the routing gets saner.

Hi. I didn't know which map option to choose so i went with the first option "generic routable". The file size for the unit seems ok. Do others have a better suggestion ? The new style one does appear to have more sueful detail from the wiki description. What is everyone's experience ?

I tried the same roundabout with my 830 and saw the same issue.  I create my own maps and don't tweak the routing during map creation for a particular mode of transport.

I have just tried setting the routing mode to automobile driving and the issue is fixed.  It seems that in road cycling navigation mode it ignores motorways so can't count motorway exits from roundabouts where as it should not route down motorways but acknowledge their existence to correctly count junction exits.

Okay, so if you used the generic one then what I wrote is not the problem. I personally like the style of the openfietsmap lite, so I'm using the style file from it to generate my own maps, but I don't touch the routing (so it's generic and I have the Edge set to Road Cycling).

Wongataa- it's very interesting investigation about the routing of that roundabout, so it does look like a small bug in the Edge's routing engine. I usually just look at the map and don't have the instructions enabled, so I haven't run into this problem before.
