Ah, that’s why my maps have all different FID’s, I forgot. Guess the MapSource programming team never understood how to properly implement families with products, tssk. 
The family ID should be in the range from 1 to 65535 (because it’s stored as a 16 bit uint in the TDB file).
Don’t use 2041; that’s the family ID of the global basemap in BaseCamp.
multiple PID’s were only used for special combined maps like the old Bluechart, or for maps without a FID.
New attempt:

Both BaseCamp and JaVaWa GMTK don’t complain. I would appreciate it if someone with OSX can check out the Mac version. I haven’t checked on the GPS yet too, my GPSmap 60 isn’t feeling well since I dropped it on the road at high speed 
Note: the country says Burundi, but the area looks more like Qatar. This is not a but, it is because I updated the version but didn’t update the tile list in my test request.
-I see a lot of img files in the download list, probably not intended?
-osm_generic_windows.exe After installation I see two tiles, Burundi and Malawi, with a large gap (1000 km) between them, but the intention is good 
-OSM generic routable(Burundi) family name looks good now, it shows in Mapsource with the version date, so far so good.
-FID looks ok
-installation is still the old way (but with mkgmap r3186 this is solved)
-“Mac” version is also good
-osm_generic_tiles.zip lacks the ovm files (they are now in the download list, ovm_63241023.img ovm_63241017.img)
-osm_generic_gmapsupp.zip havent tested it, looks ok with gmaptool.
Can you upload a mapset with a typ file (or a generic new style mapset)?
Is it possible to move or hide unnecessary files like tiles.txt, country.txt, 23108000.nsi file?
Maybe put the 23108000.nsi only in the osm_generic_tiles.zip?
BTW I hope the TS won’t get confused with all this detailed info
Yes, I forgot to mention that I temporarily disabled cleanup before publication.
Great.
Ah, I wondered why I didn’t notice any changes, it all seemed so ‘regular’
That’s a bug. Solved it, I think.
Yes:

The OpenFietsMap Lite map below also has unimportant files moved to a subdirectory:
http://osm.pleiades.uni-wuppertal.de/garmin/openfietsmap_lite/10-04-2014/24718f14af9f8d6703fd6bb3c0792d88/
Somehow the macosx.zip file is not recognised anymore by htaccess/Apache. Icon and description are missing, can’t find the cause, it’s working fine for other maps.
Ah, yes this is an old wish, I’ll move these to a subdirectory ‘metadata’.
When we’re done I’ll split off the discussion and merge with the main topic. 
In the htaccess I see this line:
AddDescription "<b>Map installer for RoadTrip on the Mac OSX platform.</b>" roadtrip.zip
Perhaps change it into
AddDescription "<b>Map installer for Basecamp / Mac OSX platform.</b>" macosx.zip
Roadtrip is replaced by Basecamp (btw you can use this format also for Basecamp under Windows).
Replace roadtrip.zip for macosx.zip in this line too:
# Add icons to specific files
AddIcon /garmin/icons/macos.gif roadtrip.zip
The TYP file is missing in all files.
Don’t know for sure, but it looks like I somehow got an old htaccess source file in my test directory. Listing works again after updating it. 
Indeed it was. But not anymore 
Everything is fine now! 
Great, I’ll put the adapted script in production. 
Edit:
Hmm, no, I’ll wait until I’ve updated Mkgmap and tested the new NSIS installer script as well.
Edit:
The map is updated with the latest Mkgmap and the installer seems to work fine. An update is in order.
Edit:
The new script is now in production on the country server. Many thanks to Ligfietser and JaVaWa for the tips, suggestions and testing!
Enjoy!
Made a small improvement to the website that removes the "- " from Canadian and US states wherever it’s used (except in the pull-down menu’s). This was needed because matching “- Alberta” against “Alberta” to get it’s country code does not work well.
Also fixed a few missing or mismatched country codes.
Thanks Lambertus!
In the generic new styles there were some routing errors detected (see http://forum.openstreetmap.org/viewtopic.php?pid=414084)) which had to do with opposite cycleways.
I corrected those in the style file, but now it needs the internal –make-opposite-cycleways option instead of the rules that I put in the lines style (but that wasnt working).
Can you add the option --make-opposite-cycleways to the generic new process (dont know if the generic old already has this option? The OFM Lite does not need this).
Added the parameter to Generic New, Generic Old does not have this parameter so I added it there too. Is that OK?
Yep, it has been improved recently by Gerd so I guess its ok to use.
Cool. I’m also experimenting a bit with nicer indexing: http://osm.pleiades.uni-wuppertal.de/garmin/generic_new/16-04-2014/55ec29e103f4e439ab9a2904598f3ce3/
Nice, much better. Maybe instead of the footer Apache/2.2.22 (Ubuntu) Server etc add a license note from *_license.txt?

BTW I dont see “new” in the mapname, it says “OSM generic routable(Netherlands)”
http://osm.pleiades.uni-wuppertal.de/garmin/generic_new/16-04-2014/55ec29e103f4e439ab9a2904598f3ce3/metadata/24528000.nsi
Hmm. I wonder if there is a way of determing the date of the OSM data being used. I’ve made updates to various places in New Jersey, US and they aren’t in the garmin maps downloaded from openfietsmap.nl.
It’s not perfect, but the date of the map gives an idea. This date is when the update process started and one of the first things the process does is updating the local copy of the OSM planet with daily extracts. The local planet is at least one day behind the start date (and in some cases it can be two days).
The rule of thumb is therefore the version date minus two days.
If I look in the download box of for instance Iceland, it also shows
country: Netherlands
version: 16-04-2014
http://osm.pleiades.uni-wuppertal.de/garmin/generic_new/16-04-2014/0b3a65f8b63d4fc923520dd76deaa26a/
I also noticed that the new version and the old version both have the same name: OSM generic routable(Netherlands)
This means that if I install the new version first, and afterwards the old, it warns that a previous map has been found.
So this is not too bad. You can either install the old version or the new style version, not both.
If we want them both, the map name of the new style should be different: OSM generic routable new (Netherlands)
That is a very dumb copy/paste error on my part. Fixed in the code.
The description is changed to OSM generic routable new.
As always: thanks for the feedback, Ligfietser!
