I updated mkgmap to r1337, and found that my overview img/tdb changed names. I adjusted gmapibuilder invocation to reference those, and that succeeded. But on loading into roadtrip I get a "The map you selected contains some errors and cannot be displayed. The default map is being shown instead." popup.

I checked out your script, and found that the problem probably is caused by gmapi-builder. - File OSM_gdt_series.gmapi was missing the overview map (osmmap.img). - I used the same map files and converted them using Garmin's Mapconvert program. This time, osmmap.img was properly converted into the gmapi package. I haven't bothered to look, but it could be that gmapi-builder expects only numeric values for the name of the overview map. At any rate, I have not encountered such problems, perhaps because I always set the -- overview-mapname option to a numeric value. - You might try setting --overview-mapname=63240000 and see if this makes any difference.
