[mkgmap-dev] Roundabouts causes crashing devices

Fri Jul 8 09:49:53 BST 2016

Hi list,
Many users of my Openfietsmap are reporting crashes when approaching roundabouts.
Some notice it before they enter the roundabout, others report that the device dies on the roundabout itself.
In many cases those roundabouts are with cycle routes, so I have removed the bicycle routes from those roundabouts. Some report this fix works, others still complain of crashing the device. There are also cases without any cycle route involved so I wonder if this happens only with my maps.

It happens with recent GPS devices like the Oregon 6xx series, Garmin Edge Touring and 8xx, GPS map 62 and 64.
It does not happen with older devices. I cannot find any roundabout in my vicinty to reproduce it so it does not happen all the time with every firmware. The only thing that all those reports have in common is that it happens near a roundabout, the device is dying slowly, turning it back on will make it work again.

Did anyone here have seen the same behaviour?
