can you tell me is there a way to merge maps downloaded extract.bbbike.org?
I’ve downloaded four Openfietsmap Lite maps for Garmin Edge 530 and I’ve tried to merge them with OSM Combiner.
Unfortunately all these maps share same mapid (starting from 48860001…). Renaming tile files didn’t worked.
Of course I can upload these maps to Garmin Edge but I’d like to avoid overlapping.
I’d still expect routing problems (large detours or crashes or direct lines) across tile boundaries where the tiles where not in the same mapset. You didn’t write if the four downloaded maps cover distint areas or if they are overlapping, so I can only guess.
So for example 93020001 will be to 94020001 and so on.
Of course you have to make sure 94020001 isn’t already in use in other mapsets
Also the name of the new mapset must be corrected (could be done with Javawa’s Device manager as well)
Please note that overlapping maptiles can still be problematic with routing.
The Map name and PID can be changed with JaVaWa GTMK https://www.javawa.nl/gmtk_en.html
which has a GUI, and therefore easier to use than command lines.
Note that the maps must already be installed in Basecamp to show up in GTMK
