Hello everybody, Opentopomap for Garmin seems to have a rendering issue along the borders of Germany when used with gpsmap 65s (the only device I can test this on).
In some regions close to the border to France, large rectangular gaps appear in the Garmin map on my 65s but not in the Basecamp version of OTM-Germany. This is visible in the Black Forest but also in other areas along the DE-FR border. On the Garmin GPSMAP 65s, these regions are cross-hatched and do not show the world map either. It does not depend on the zoom level and does not disappear if OTM maps for France and Switzerland are installed/active/inactive as well. It also persists if I download a new OTM version.

A screenshot is available here: screenshot

Does anyone have an idea what could be the cause or whom I could contact to report this as a bug?

Looking at the web version it looks ok. I think the problem is with that particular download of opentopomap for your garmin. They issue updates and sometimes it goes wrong. The creators of the download would have to test it with a garmin each time, which, as we know takes a bit of time. They may not go through that check each time they do an update. I download England's opentopo occasionally and once it didn't work, but it's usually an excellent version of OSM for a garmin, there maybe a contact on the site, or just wait for a re-issue. NOTE I have not used basecamp much recently but i think you could send bits of the basecamp version to your garmin, although not the contours?? because of the separate layers, just an idea.

Hi, thanks for your reply. The issue in your thread does sound similar. In my case it does not seem to be an issue with a particular download since I tried it with downloads from different dates across several weeks (if the date of the map means anything) and they all showed the same gaps. It looks as if certain tiles are not added to the Garmin version. The website has no contact option, or none that I could find.
I could not find a way to upload the actual OTM basecamp map to the Garmin device. My mapinstall is newer than the one referenced in your thread, but it doesn't upload the map either (it does allow to upload another map, though).

You may find a contact here but they are volunteers. They may see this question and then fix it. edit and there is a report errors link in the text.
