[mkgmap-dev] Roundabouts causes crashing devices

From Gerd Petermann GPetermann_muenchen at hotmail.com on Fri Jul 8 10:02:20 BST 2016

Hi Minko,

for my trip to Sicilia I used a map from http://garmin.openstreetmap.nl/using the Openfietsmap Lite

style. I also noticed quite a lot of crashes (maybe one per day) on my Oregon 600. I did not relate that to

roundabouts but in Italy a roundabout is never far away.

Most of the time I followed a track, so I think they were not related to routes.

BUT in one case the device crashed two times within a short time, and yes, I was aproaching a roundabout and

using a route calculated by the device.

I still have the recorded gpx files and the img file for the map in case these can help you.

Betreff: [mkgmap-dev] Roundabouts causes crashing devices

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?
